Commit e1da5f953731b4e2990e054d09ec0bcb2e5146b8 in lucene-solr's branch
refs/heads/master from [~jim.ferenczi]
[ https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=e1da5f9 ]
LUCENE-8531: QueryBuilder#analyzeGraphPhrase now creates one phrase query per
finite strings in the graph if the slop is greater than 0.
Span queries cannot be used in this case because they don't handle slop the
same way than phrase queries.
> QueryBuilder hard-codes inOrder=true for generated sloppy span near queries

> QueryBuilder.analyzeGraphPhrase() generates SpanNearQuery-s with passed-in
> phraseSlop, but hard-codes inOrder ctor param as true.
> Before multi-term synonym support and graph token streams introduced the
> possibility of generating SpanNearQuery-s, QueryBuilder generated
> (Multi)PhraseQuery-s, which always interpret slop as allowing reordering
> edits. Solr's eDismax query parser generates phrase queries when its
> pf/pf2/pf3 params are specified, and when multi-term synonyms are used with a
> graph-aware synonym filter, SpanNearQuery-s are generated that require
> clauses to be in order; unlike with (Multi)PhraseQuery-s, reordering edits
> are not allowed, so this is a kind of regression. See SOLR-12243 for edismax
> pf/pf2/pf3 context. (Note that the patch on SOLR-12243 also addresses
> another problem that blocks eDismax from generating queries *at all* under
> the above-described circumstances.)
> I propose adding a new analyzeGraphPhrase() method that allows configuration
> of inOrder, which would allow eDismax to specify inOrder=false. The existing
> analyzeGraphPhrase() method would remain with its hard-coded inOrder=true, so
> existing client behavior would remain unchanged.
