Configuration of Solr Cell
==========================

.. note::

      All Apache Solr versions prior v. 9.10.1 are vulnerable
      against `CVE-2025-66516 / CVE-2025-54988 <https://solr.apache.org/security.html#cve-2025-66516-apache-solr-extraction-module-vulnerable-to-xxe-attacks-via-xfa-content-in-pdfs>`_
      please update or apply the proposed mitigation in solrconfig.xml
      and set :php:`$GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['tika']['skipSecurityChecks'] = true` on EXT:tika v 13.1.0+
      if you can not update the Apache Solr server.


Requirements
------------

* Running and configured Apache Solr service.

.. tip::

  For example `the dkds Hosted-Solr <https://hosted-solr.com/en/>`_

* Setting EXT:tika to use the Apache Solr server connection.

Setup EXT:tika for Solr Server
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Open Extension settings for EXT:tika **General** tab and choose **"Solr Server"** as **Extractor.**

.. tip::

       All settings of Solr accept the :php:`%env(<SOME_SOLR_ENV_VAR>)%` syntax like on site-config now.

       If the settings for :php:`solrUsername` or :php:`solrPassword` do not contain the :php:`%env(<SOME_SOLR_ENV_VAR>)%`,
       then they are blinded/hidden, to avoid the accidental release of secrets and credentials via TYPO3 backend configuration Tools like:

       * Extension Settings module
       * Configuration module


See :ref:`Check if it works <configuration-tika-check>` for test instructions.
