# Elasticsearch analyzer

The Elasticsearch analyzer performs the analysis process of the search database.

Mahara uses the built-in mahara_analyzer.

Read the Elasticsearch instructions if you wish to use a different analyzer.

This setting cannot be changed through the web interface. You may change it by setting a value in your config.php file for the following config variable:

`$cfg->plugin_search_elasticsearch_analyzer`.

It is recommended that you don't change the default "mahara_analyzer" unless you know what you are doing.
