Yonik Seeley commented on SOLR-9185:
------------------------------------

bq. The current behavior might be counter to a new user's expectations, but if 
we just change how it works by default, a lot of existing users might suddenly 
be surprised by very different behavior from Solr 

+1, it's been this way since the beginning of Lucene.  It's not a bug (esp 
since in the past multiple terms were treated as a phrase query, and still are 
depending on configuration - think word delimiter filter).

bq. I suppose we could add luceneMatchVersion-sensitive code 

That's a very blunt hammer ;-)
It would be nice if we could selectively keep the old behavior, but I'm not 
sure how difficult that would be w/o duplicating the whole parser.

> 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'.
