Steve Rowe commented on LUCENE-7533:
------------------------------------
FYI autoGeneratePhraseQueries was never added to the flexible query parser.
> Classic query parser: autoGeneratePhraseQueries=true doesn't work when
> splitOnWhitespace=false

> Key: LUCENE-7533
> URL: https://issues.apache.org/jira/browse/LUCENE-7533
> Project: Lucene - Core
> Issue Type: Bug
> Affects Versions: 6.2, 6.3, 6.2.1
> Reporter: Steve Rowe
> Attachments: LUCENE-7533.patch

>
> LUCENE-2605 introduced the classic query parser option to not split on
> whitespace prior to performing analysis.
> When splitOnWhitespace=false, the output from analysis can now come from
> multiple whitespace-separated tokens, which breaks code assumptions when
> autoGeneratePhraseQueries=true: for this combination of options, it's not
> appropriate to auto-quote multiple non-overlapping tokens produced by
> analysis. E.g. simple whitespace tokenization over the query "some words"
> will produce the token sequence ("some", "words"), and even when
> autoGeneratePhraseQueries=true, we should not be creating a phrase query here.
