> 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'.
