> 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.
