tx_solr.index

This part contains all configuration that is required to setup your indexing configuration. You can use EXT:solr to easily index pages or any kind of records of your TYPO3 CMS.

Allows to prevent frontend indexing of pages when a backend editor is logged in and browsing the website.

additionalFields (deprecated)

Type:String, cObject (since 1.1) TS Path:plugin.tx_solr.index.additionalFields Since:1.0 Deprecated:2.0

A mapping of Solr field names to additional string values to be indexed with page documents. Use dynamic fields to index additional data, this way you don’t have to modify the schema.xml

Example:

plugin.tx_solr.index.additionalFields {
  myFirstAdditionalField_stringS = some string

  mySecondAdditionalField_stringS = TEXT
  mySecondAdditionalField_stringS {
    value = some other value that can be constructed using any TypoScript cObject
    case = upper
    // more processing here as needed
  }
}

Since version 1.1 you can use cObjects to generate the value for the field. The only thing to observe is that you generate strings. Other values may work, but haven’t been tested yet.

Deprecated since 2.0, please use the Index Queue indexing configurations instead as it allows you to define more precisely for which types of documents you want which fields to be indexed.

fieldProcessingInstructions

Type:cObject TS Path:plugin.tx_solr.index.fieldProcessingInstructions Since:1.2 2.0 Options:timestampToIsoDate, uppercase, pathToHierarchy (2.5-dkd), pageUidToHierarchy (2.5-dkd)

Assigns processing instructions to Solr fields during indexing (Syntax: Solr index field = processing instruction name). Currently it is not possible to extend / add own processing instructions. Before documents are sent to the Solr server they are processed by the field processor service. Currently you can make a filed’s value all uppercase, convert a UNIX timestamp to an ISO date, or transform a path into a hierarchy for hierarchical facets (2.0 only). Currently you can use only one processing instruction at a time.

Example:

fieldProcessingInstructions {
    changed = timestampToIsoDate
    created = timestampToIsoDate
    endtime = timestampToIsoDate
}

queue

The Index Queue is a powerful feature introduced with version 2.0. It allows you to easily index any table in your TYPO3 installation by defining a mapping of SolrFieldName = DatabaseTableFieldNameOrContentObject. The table must be configured / described in TCA, though. To index other, external data sources you might want to check out Solr’s Data Import Handler (DIH).

The Index Queue comes preconfigured to index pages (enabled by default) and an example configuration for tt_news (provided as a separate TypoScript template).

Type:Array TS Path:plugin.tx_solr.index.queue Since:2.0 Default:pages

Defines a set of table indexing configurations. By convention the name of the indexing configuration also represents the table name. You can name the indexing configuration differently though by explicitly defining the table as a parameter within the indexing configuration. That’s useful when indexing records from one table with different configuration - different single view pages / URLs for example.

Example:

// enables indexing of tt_news records
plugin.tx_solr.index.queue.news = 1
plugin.tx_solr.index.queue.news.fields {
    abstract = short
    author = author
    description = short
    title = title

    // the special SOLR_CONTENT content object cleans HTML and RTE fields
    content = SOLR_CONTENT
    content {
        field = bodytext
    }

    // the special SOLR_RELATION content object resolves relations
    category_stringM = SOLR_RELATION
    category_stringM {
        localField = category
        multiValue = 1
    }

    // the special SOLR_MULTIVALUE content object allows to index multivalue fields
    keywords = SOLR_MULTIVALUE
    keywords {
        field = keywords
    }

    // build the URL through typolink, make sure to use returnLast = url
    url = TEXT
    url {
        typolink.parameter = {$plugin.tt_news.singlePid}
        typolink.additionalParams = &tx_ttnews[tt_news]={field:uid}
        typolink.additionalParams.insertData = 1
        typolink.returnLast = url
        typolink.useCacheHash = 1
    }

    sortAuthor_stringS = author
    sortTitle_stringS  = title
}

queue.[indexConfig]

Type:Boolean, Array TS Path:plugin.tx_solr.index.queue.[indexConfig] Since:2.0 Default:pages

An indexing configuration defines several parameters about how to index records of a table. By default the name of the indexing configuration is also the name of the table to index.

By setting plugin.tx_solr.index.queue.[indexConfig] = 1 or 0 you can en- / disable an indexing configuration.

Note: you could add L={field:__solr_index_language} in the additionalParams of the typolink to link to the correct language version (this was removed from the example above to simplify the example)

queue.[indexConfig].additionalWhereClause

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].additionalWhereClause Since:2.0

A WHERE clause that is used when initializing the Index Queue, limiting what goes into the Queue. Use this to limit records by page ID or the like.

// only index standard and mount pages, enabled for search
plugin.tx_solr.index.queue.pages.additionalWhereClause = doktype IN(1, 7)

queue.[indexConfig].initialPagesAdditionalWhereClause

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].initialPagesAdditionalWhereClause Since:6.1

A WHERE clause that is used when initializing the Index Queue, limiting pages that goes into the Queue. This filter is applied prior to the plugin.tx_solr.index.queue.[indexConfig].additionalWhereClause filter and hence provides an even stronger filter mechanism - since it can be used to filter away page ID’s that shouldn’t be processed at all.

// Filter away pages that are "spacer" and have no_search, hidden and nav_hide set to zero
plugin.tx_solr.index.queue.pages.initialPagesAdditionalWhereClause = doktype <> 199 AND no_search = 0 AND hidden = 0 AND nav_hide = 0

queue.[indexConfig].additionalPageIds

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].additionalPageIds Since:2.0

Defines additional pages to take into account when indexing records for example. Especially useful for indexing DAM records or if you have your news outside your site root in a shared folder to use for multiple sites.

Additional page IDs can be provided as comma-separated list.

queue.[indexConfig].table

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].table Since:2.0

Sometimes you may want to index records from a table with different configurations, f.e., to generate different single view URLs for tt_news records depending on their category or storage page ID. In these cases you can use a distinct name for the configuration and define the table explicitly.

plugin.tx_solr.index.queue.generalNews {
  table = tt_news
  fields.url = URL for the general news
  // more field configurations here ...
}

// extends the general news configuration
plugin.tx_solr.index.queue.pressNews < plugin.tx_solr.index.queue.generalNews
plugin.tx_solr.index.queue.pressNews {
  fields.url = overwriting URL for the press announcements
  // may overwrite or unset more settings from the general configuration
}

// completely different configuration
plugin.tx_solr.index.queue.productNews {
  table = tt_news
  fields.url = URL for the product news
}

queue.[indexConfig].initialization

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].initialization Since:2.0

When initializing the Index Queue through the search backend module the queue tries to determine what records need to be indexed. Usually the default initializer will be enough for this purpose, but this option allows to define a class that will be used to initialize and add records to the Index Queue in special ways.

The extension uses this option for initializing the pages and more specifically to resolve Mount Page trees so they can be indexed too, although only being virtual pages.

queue.[indexConfig].indexer

Type:String, Array TS Path:plugin.tx_solr.index.queue.[indexConfig].indexer Since:2.0

When configuring tables to index a default indexer is used that comes with the extensions. The default indexer resolves the Solr field to database table field mapping as configured. However, in some cases you may reach the limits of TypoScript, when this happens you can configure a specialized indexer using this setting.

The indexer class is loaded using TYPO3’s auto loading mechanism, so make sure your class is registered properly. The indexer must extend tx_solr_indexqueue_Indexer.

Example, pages use a specialized indexer:

plugin.tx_solr.index.queue.pages {
    indexer = tx_solr_indexqueue_PageIndexer
    indexer {
        // add options for the indexer here
    }
}

Within the indexer configuration you can also define options for the specialized indexer. These are then available within the indexer class in $this->options.

Example, the TypoScript settings are available in PHP:

TypoScript:

plugin.tx_solr.index.queue.myIndexingConfiguration {
    indexer = tx_myextension_indexqueue_MyIndexer
    indexer {
        someOption = x
        someOtherOption = y
    }
}

PHP:

namespace MyVendor\Namespace;

use ApacheSolrForTypo3\Solr\IndexQueue\Indexer;

class MyIndexer extends Indexer {
  public function index(tx_solr_indexqueue_Item $item) {
    if ($this->options['someOption']) {
      // ...
    }
  }
}

queue.[indexConfig].indexingPriority

Type:Integer TS Path:plugin.tx_solr.index.queue.[indexConfig].indexingPriority Since:2.2 Default:0

Allows to define the order in which Index Queue items of different kinds are indexed. Items with higher priority are indexed first.

queue.[indexConfig].fields

Type:Array TS Path:plugin.tx_solr.index.queue.[indexConfig].fields Since:2.0

Mapping of Solr field names on the left side to database table field names or content objects on the right side. You must at least provide the title, content, and url fields. TYPO3 system fields like uid, pid, crdate, tstamp and so on are added automatically by the indexer depending on the TCA information of a table.

Example:

plugin.tx_solr.index.queue.[indexConfig].fields {
  content = bodytext
  title = title
  url = TEXT
  url {
    typolink.parameter = {$plugin.tx_extensionkey.singlePid}
    typolink.additionalParams = &tx_extenionkey[record]={field:uid}
    typolink.additionalParams.insertData = 1
    typolink.returnLast = url
  }
}

queue.[indexConfig].attachments.fields

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].attachments.fields Since:2.5-dkd

Comma-separated list of fields that hold files. Using this setting allows to tell the file indexer in which fields to look for files to index from records.

Example:

plugin.tx_solr.index.queue.tt_news.attachments.fields = news_files

queue.[indexConfig].recursiveUpdateFields

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].recursiveUpdateFields Since:6.1 Default:Empty

Allows to define a list of additional fields from the pages table that will trigger a recursive update.

plugin.tx_solr.index.queue.pages.recursiveUpdateFields = title

The example above will trigger a recursive update of pages if the title is changed.

Please note that the following columns should NOT be configured as recursive update fields: “hidden” and “extendToSubpages”. These fields are handled by EXT:solr already internally and thus they will have not effect.

queue.pages.excludeContentByClass

Type:String TS Path:plugin.tx_solr.index.queue.pages.excludeContentByClass Since:4.0

Can be used for page indexing to exclude a certain css class to be indexed.

Example:

plugin.tx_solr.index.queue.pages.excludeContentByClass = removeme

The example above will remove the content of items in the page that have the css class “removeme”.

queue.pages.allowedPageTypes

Type:List of Integers TS Path:plugin.tx_solr.index.queue.pages.allowedPageTypes Since:3.0 Default:1,7

Allows to set the pages types allowed to be indexed.

Even if you have multiple queues for pages, e.g. via different additionalWhereClause’s, you have to set this value to allow further doktype’s. Restrict the pages to be indexed by each queue via additionalWhereClause.

queue.pages.indexer.authorization.username

Type:String TS Path:plugin.tx_solr.index.queue.pages.indexer.authorization.username Since:2.0

Specifies the username to use when indexing pages protected by htaccess.

queue.pages.indexer.authorization.password

Type:String TS Path:plugin.tx_solr.index.queue.pages.indexer.authorization.password Since:2.0

Specifies the password to use when indexing pages protected by htaccess.

queue.pages.indexer.frontendDataHelper.scheme

Type:String TS Path:plugin.tx_solr.index.queue.pages.indexer.frontendDataHelper.scheme Since:2.0

Specifies the scheme to use when indexing pages.

queue.pages.indexer.frontendDataHelper.host

Type:String TS Path:plugin.tx_solr.index.queue.pages.indexer.frontendDataHelper.host Since:2.0

Specifies the host to use when indexing pages.

queue.pages.indexer.frontendDataHelper.path

Type:String TS Path:plugin.tx_solr.index.queue.pages.indexer.frontendDataHelper.path Since:2.0

Specifies the path to use when indexing pages.

Indexing Helpers

To make life even easier the Index Queue provides some indexing helpers. These helpers are content objects that perform cleanup tasks or content transformations.

SOLR_CONTENT

Since:2.0

Cleans a database field in a way so that it can be used to fill a Solr document’s content field. It removes HTML markup, Javascript and invalid utf-8 chracters.

The helper supports stdWrap on its configuration root.

Example:

content = SOLR_CONTENT
content {
    field = bodytext
}

Parameters:

value

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].value Since:2.0

Defines the content to clean up. In this case the value would be hard-coded.

SOLR_MULTIVALUE

Since:2.0

Turns comma separated strings into an array to be used in a multi value field of an Solr document.

The helper supports stdWrap on its configuration root.

Example:

keywords = SOLR_MULTIVALUE
keywords {
    field = tags
    separator = ,
    removeEmptyValues = 1
}

Parameters:

value

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].value Since:2.0

Defines the content to clean up. In this case the value would be hard-coded.

separator

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].separator Since:2.0 Default:,

The separator by which to split the content.

removeEmptyValues

Type:Boolean TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].removeEmptyValues Since:2.0 Options:0,1 Default:1

The helper will clean the resulting array from empty values by default. If, for some reason, you want to keep empty values just set this to 0.

removeDuplicateValues

Type:Boolean TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].removeDuplicateValues Since:2.9 Options:0,1 Default:0

Cleans the result from duplicate values.

SOLR_RELATION

Since:2.0

Resolves relations between tables.

Example:

category_stringM = SOLR_RELATION
category_stringM {
    localField = category
    multiValue = 1
}

Parameters:

localField

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].localField Since:2.0 Required:yes

The current record’s field name to use to resolve the relation to the foreign table.

foreignLabelField

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].foreignLabelField Since:2.0

Usually the label field to retrieve from the related records is determined automatically using TCA, using this option the desired field can be specified explicitly. To specify the label field for recursive relations, the field names can be separated by a dot, e.g. for a category hierarchy to get the name of the parent category one could use “parent.name” (since version:2.9).

multiValue

Type:Boolean TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].multiValue Since:2.0 Options:0,1 Default:0

Whether to return related records suitable for a multi value field. If this is disabled the related values will be concatenated using the following singleValueGlue.

singleValueGlue

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].singleValueGlue Since:2.0 Default:“, “

When not using multiValue, the related records need to be concatenated using a glue string, by default this is “, ” (comma followed by space). Using this option a custom glue can be specified. The custom value must be wrapped by pipe (|) characters to be able to have leading or trailing spaces.

relationTableSortingField

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].relationTableSortingField Since:2.2

Field in an mm relation table to sort by, usually “sorting”.

enableRecursiveValueResolution

Type:Boolean TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].enableRecursiveValueResolution Since:2.9 Options:0,1 Default:1

If the specified remote table’s label field is a relation to another table, the value will be resolve by following the relation recursively.

removeEmptyValues

Type:Boolean TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].removeEmptyValues Since:2.9 Options:0,1 Default:1

Removes empty values when resolving relations.

removeDuplicateValues

Type:Boolean TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].removeDuplicateValues Since:2.9 Options:0,1 Default:0

Removes duplicate values

additionalWhereClause

Type:String TS Path:plugin.tx_solr.index.queue.[indexConfig].fields.[fieldName].additionalWhereClause Since:5.0

Where clause that could be used to limit the related items to a subset that matches this where clause

Example:

category_stringM = SOLR_RELATION
category_stringM {
    localField = tags
    multiValue = 1
    additionalWhereClause = pid=2
}

enableCommits

Type:Boolean TS Path:plugin.tx_solr.index.enableCommits Since:6.1 Default:true

This setting controls whether ext-solr will implicitly cause solr commits as part of its operation.

If this settings is set to false, you need to ensure that something else will periodically call commits. The solr daemons AutoCommit feature would be a natural choice.

This feature is mainly useful, when you have many installations in the same solr core.

Note: Calling some APIs may still cause commits, but these can always be explicitly disabled.
