Bug ID: 62726
Summary: CirrusSearch: If the search didn't find many results
then rerun the suggester with more time consuming
settings
Product: MediaWiki extensions
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: CirrusSearch

After https://gerrit.wikimedia.org/r/#/c/119041/ we will be running the
suggester with faster, less accurate settings. They'll be good enough to find
lots of suggestions, but not all.
Proposal: if the search didn't find many results then rerun the suggester with
more aggressive settings. Stuff like:
prefix_length: 1,
max_errors: 3,
confidence: 1.1,
Also, we might want to only do this if the suggest run with the query didn't
find anything. Not sure. We could also check the score on the result and use
some cutoff. Dunno.
Note: prefix_length and max_errors can cause much more CPU usage. I'm
suggesting just a single notch more on each setting but that still would be
quite a bit.
