Steve Rowe updated SOLR-10357:
------------------------------
Attachment: SOLR-10357.patch
Patch implementing the idea.
There remains an issue: the original auto-gen use case (for e.g. {{wifi => wi
fi}}, replacing a single token with multiple tokens, but no overlapping terms)
still doesn't auto-generate a phrase query for `wi fi` if synonyms are replaced
rather than expanded when {{QueryBuilder.autoGenerateMultiTermSynonymsQuery}}
is set to {{true}}. So this is not (yet) a complete solution. IMHO this is a
weakness of how {{QueryBuilder}} decides whether to invoke "graph" processing,
currently only when a posLength > 1 is encountered (as when there are
*overlapping* multi-word synonyms).
This patch changes the test schema named {{schema12.xml}} to use the
graph-aware versions of the synonym and word delimiter filters. Instead of
committing as-is (pending full testing and precommit, not yet done), I'll do
the rote schema conversions on SOLR-10343 and SOLR-10344 and set those as
blockers of this issue; that seems like a more appropriate way to handle
whatever conflicts might come up from other uses of {{schema12.xml}}.

> Right now, the options to not split on whitespace ({{sow=false}}) and to
> autogenerate phrase queries ({{autoGeneratePhraseQueries="true"}}) will cause
> queries to throw an exception, since they are incompatible.
> {{QueryBuilder.autoGenerateMultiTermSynonymsPhraseQuery}}, introduced in
> LUCENE-7638, is the graph query version of Solr's per-fieldtype
> {{autoGeneratePhraseQueries}} option, and is not incompatible with
> {{sow=false}}.
> So {{autoGeneratePhraseQueries="true"}} should cause
> {{QueryBuilder.autoGenerateMultiTermSynonymsPhraseQuery}} to be set to true
> when {{sow=false}}, rather than triggering an exception.
