Bjarke Mortensen commented on SOLR-10078:
-----------------------------------------
I see that this issue is attached to the highlighter component. This is not
correct. It affects all parts of querying with the ComplexPhraseQuery.
[~dsmiley], [~steve_rowe] would any of you be able to change the component, so
that it can get looked at by the correct people, assuming that you are not
those people?
The pull request is ~7months old now, but still merges cleanly with master, so
it would be really nice if this could get included soon.

> I did NOT have this error in Solr v6.1 so something has changed in v6.3 that
> is causing this error.
> Steve Rowe thinks it may be related to
> https://issues.apache.org/jira/browse/LUCENE-7337
> Hoss' initial thoughts: "i think the root of the issue is that the way those
> fuzzy and prefix queries are parsed means that they *may* produce an empty
> boolean query depending on the contents of the index, and then the new
> optimization rewrites those empty boolean queries into MatchNoDocsQueries --
> but the highlighter (which uses hueristics to figure out what to ask each
> query -- based on it's type -- what to highlight) doesn't know what to do
> with that. i'm really suprised the highlighter throws an error in the
> "unexpected query type" code path instead of just ignorning it."
