--------------------------------------

bq. query the exact value of a field 
Can you give an example? You mean values containing special characters? like ! || ? * ~  etc.

> The StandardSyntaxParser.jj has (undocumented?) support for the <, <=, > and => operators that generate a TermRangeQueryNode. The equal operator, however, behaves just like the colon and produces a regular Term node instead of a TermRangeQueryNode.
> I've been using the attached patch in a project where we had to be able to query the exact value of a field and I'm hoping there is interest to apply it upstream.
> (Note that the colon operator works just as before, producing TermQuery or PhraseQuery nodes.)
