Jim Ferenczi commented on LUCENE-7799:
--------------------------------------
Then we should maybe remove {{autoGenerateMultiTermSynonymsPhraseQuery}} and
make {{autoGeneratePhraseQueries}} applicable to graph and non-graph query even
when {{splitOnWhitespace=false}}. A nice side effect of this change is that it
would correctly handle a simple synonym rule like "ny, new york". With
{{autoGeneratePhraseQueries=true}} "new york" would be matched as a phrase
query with the input query "ny" and as a simple disjunction with the input
query "new york". Of course this should also be true when "ny" is preserved in
the output (when graph processing is involved) which is why I think it is
important to have a single option for graph and non-graph query.
> Classic query parser should allow autoGeneratePhraseQueries=true when
> splitOnWhitespace=false

> Project: Lucene - Core
> Issue Type: Bug
> Components: core/queryparser
> Reporter: Steve Rowe
>
> LUCENE-7533 disabled the option combination
> {{splitOnWhitespace=false}}/{{autoGeneratePhraseQueries=true}} because of how
> {{autoGeneratePhraseQueries=true}} is handled: a query chunk is treated as if
> it were literally quoted. When {{splitOnWhitespace=false}}, a query chunk
> can be multiple whitespace-separated words, and auto-quoting multiple terms
> will produce inappropriate phrase queries.
> I have an idea about how to fix this: {{autoGeneratePhraseQueries=true}} is
> supposed to cause phrase queries to be constructed when multiple analyzed
> terms result from a single query word, e.g. when WordDelimiter(Graph)Filter
> splits words up. Maybe this could be re-implemented in terms of offsets,
> since all terms from the same original term share the same offsets.
