Bruno Roustant commented on SOLR-14782:
---------------------------------------
I added a PR for the doc improvement. I think it will be sufficient (no need
for an UnescapeCharFilterFactory).
Thomas, you should use a StandardTokenizerFactory because with 8.3 it becomes
possible to match a subset of the query terms (not always a full match
anymore), see SOLR-11866. If you use a KeywordTokenizerFactory, it produces
only the full query as a single token, so no subset matching possible.

> h1. Description
> if the elevate.xml contains a entry with spaces:
> <{color:#0033b3}query {color}{color:#174ad4}text{color}{color:#067d17}="aaa
> bbb"{color}><{color:#0033b3}doc
> {color}{color:#174ad4}id{color}{color:#067d17}="core2docId2"
> {color}/></{color:#0033b3}query{color}>
> and the Solr query term is escaped:
> {{?q=aaa\+bbb}}
> the Solr search itself handels this correctly, but the elevate component
> "QueryElevationComponent" does not unescape the query term bevor the lookup
> in the elevate.xml.
> Result is that the entry is not elevated.
> A also valid (not escaped) query like:
> {{?q=aaa%20bbb}}
> is working.
> h1. Technical Notes
