This documentation is not using the current rendering mechanism and will be deleted by December 31st, 2020. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
This section defines general configuration options.
A switch to completely turn on / off EXT:solr. Comes in handy with multi site installations where you want to enable EXT:solr only for certain sites, but still have the extension’s configuration at a single place and include that for each site. Just set enabled = 0 for each site’s root TS template or use conditions where you do not want EXT:solr.
This also influences the connection manager; connections will be registered / detected only for enabled = 1.
If enabled, the debugQuery query parameter is added to the Solr queries. Solr will then return additional information explaining the the query, scoring, timing, and other information.
