Determine whether wikitech should really depend on production search cluster
Open, MediumPublic


When a firewall was added to the Elasticsearch servers, it blocked access from silver, causing search issues on wikitech. 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?

I know nothing about implementation, but I'd certainly prefer that search be self-contained on silver.

iirc we have done other things to island off wikitech since it is the defacto place we check for information during issues. Including, for the general elasticsearch setup :)

We could run a local instance of elasticsearch?

Could we, probably. Should we, no.

If there is an easy way to configure fallback to built-in search that would be more than reasonable to configure. Longer term T161859: Make Wikitech an SUL wiki means that keeping wikitech-static up to date for emergency use is probably the real thing to focus on.

The reasons to keep it self-contained (information available if other stuff is down) are probably also mitigated by the existence of .
