Index Maintenance¶

Solr offers a lot of request handlers to do maintenance tasks.

Committing pending documents¶

curl http://host:port/solr-path/update -H "Content-Type: text/xml"
    --data-binary '<commit />'

Clearing the index¶

curl http://host:port/solr-path/update -H "Content-Type: text/xml"
    --data-binary '<delete><query>*:*</query></delete>'

curl http://host:port/solr-path/update -H "Content-Type: text/xml"
    --data-binary '<commit />'

Optimizing the index¶

You should do this every once in a while, f.e. every day. For TYPO3, there is already a scheduler task available for this.

curl http://host:port/solr-path/update -H "Content-Type: text/xml"
    --data-binary '<optimize />'

Searching the index from the command line¶

Parameters:

q:	what to search for. Format: fieldName:fieldValue
qt:	defines the query type, for the command line we recommend “standard”, the extension itself uses “dismax”
fl:	comma separated list of fields to return
rows:	number of rows to return
start:	offset from where to return results

curl 'http://host:port/path-to-solr/select?q=hello&qt=standard&fl=title,content'

Getting information / statistics about the index¶

curl 'http://host:port/path-to-solr/admin/luke'

Create cores with the core admin api¶

The CoreAdmin API (https://cwiki.apache.org/confluence/display/solr/CoreAdmin+API) allows you, manipulate the cores in your solr server.

Since we support configSets a core could be generated with the following http call:

curl 'http://host:port/path-to-solr/admin/cores?action=CREATE&name=core_de&configSet=ext_solr_6_0_0&schema=german/schema.xml&dataDir=dataDir=../../data/german'
