Change Details

When a firewall was added to the Elasticsearch servers, it blocked access from silver, causing search issues on wikitech. https://gerrit.wikimedia.org/r/#/c/235048 fixed the issue, but I wonder whether wikitech should really depend on the search cluster working at all. I seem to recall a while back (before the lucene servers were shut down) that there was support for multiple search backends - Cirrus or Lucene (basic config options and the ability to chose them using extra parameters in the URL). I wonder if it can be made to fall back to built in MW search, or at least provide the option to use it?
