Steve Rowe updated SOLR-9751:
-----------------------------
Attachment: SOLR-9751.patch
Patch with a fix.
The problem results from a combination of lenient schema parsing and the lack
of a concept for non-user-specifiable index-time analyzers.
This patch adds a new interface {{HasImplicitIndexAnalyzer}}, implemented by
{{PreAnalyzedField}}, and schema parsing and serialization now properly handle
this case. As a result, when a field type implements
{{HasImplicitIndexAnalyzer}}, regardless of the original specified analyzer
type, an analyzer (if any) will always be specified as a query-time analyzer,
even if it was originally specified as a non-specific or index-time analyzer.
I've also adding logged warnings for cases where analyzers are specified in the
schema for field types that don't support analyzers (currently
non-{{TextField}}-s).
I'll commit once all tests and precommit pass.
