Steve Rowe updated LUCENE-7799:
-------------------------------
Component/s: core/queryparser
> Classic query parser should allow autoGeneratePhraseQueries=true when
> splitOnWhitespace=false
> ---------------------------------------------------------------------------------------------
>
> Key: LUCENE-7799
> URL: https://issues.apache.org/jira/browse/LUCENE-7799
> 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.
