Steve Rowe commented on SOLR-9185:
----------------------------------
bq. I think we need an option that turns the whitespace split off.
I disagree. I think the current behavior is counter to users' expectations, so
we should just get rid of it.
I suppose we could add luceneMatchVersion-sensitive code and include both
versions, but yuck, I'd much rather not do that.
bq. I think the default behavior in 6.x should remain unchanged. We can change
the default in master.
I disagree. I think we should change the default behavior ASAP.
bq. The implementation might take a while to become bulletproof. I suspect that
the query parser code relies heavily on the current behavior and that things
will break in unexpected ways when changing that behavior.
Here I agree. (e)dismax and other parsers that are based on the Solr clone of
the Lucene QP will need work before this change can be released.

> Project: Solr
> Issue Type: Bug
> Reporter: Steve Rowe
> Assignee: Steve Rowe
>
> Copied from LUCENE-2605:
> The queryparser parses input on whitespace, and sends each whitespace
> separated term to its own independent token stream.
> This breaks the following at query-time, because they can't see across
> whitespace boundaries:
> n-gram analysis
> shingles
> synonyms (especially multi-word for whitespace-separated languages)
> languages where a 'word' can contain whitespace (e.g. vietnamese)
> Its also rather unexpected, as users think their
> charfilters/tokenizers/tokenfilters will do the same thing at index and
> querytime, but
> in many cases they can't. Instead, preferably the queryparser would parse
> around only real 'operators'.
