***********
TYPO3 Setup
***********

The navigation plugin provides a page selection dropdown input field. The
resulting action url cannot contain a valid cHash value.

The default behaviour of TYPO3 is to call the pageNotFound handler and/or to show an exception:

.. figure:: ../Images/Configuration/typo3_pagenotfoundonchasherror.png
   :width: 800px
   :alt: TYPO3 Error-Message "Reason: Request parameters could not be validated (&cHash empty)"

   TYPO3 Error-Message "Reason: Request parameters could not be validated (&cHash empty)"

This is not the desired behaviour. You should configure in the TYPO3 install tool
$TYPO3_CONF_VARS['FE']['pageNotFoundOnCHashError']=0 to show the requested page
instead. The caching will be disabled in this case. This was the default
behaviour before TYPO3 6.x.

   TYPO3 Configuration of pageNotFoundOnCHashError in Install Tool

The install tool writes this configuration to typo3conf/LocalConfiguration.php::

    'FE' => [
            'pageNotFoundOnCHashError' => '0',
            'pageNotFound_handling' => '',
        ],

*****************
Solr Installation
*****************

This extension doesn't include Solr, but just a prepared configuration set.
To setup Apache Solr, perform the following steps:

1. Make sure you have Apache Solr 7.x up and running.
    Download Solr from http://lucene.apache.org/solr/.
    Other versions since 5.0 should be possible but are not tested.

2. Copy the lib/ApacheSolr/configsets/dlf to $SOLR_HOME/configsets/dlf.

3. Using basic authentication is optional but recommended.
    The documentation is available here:
    https://lucene.apache.org/solr/guide/7_4/basic-authentication-plugin.html
