    Description

      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'.
