Hunt.Query.Language.Parser

Version : 0.2

The Hunt query parser, based on the famous Parsec library.

The parser implements a default syntax for the query grammar which exposes all possible query types and operators to the user.

Syntax:

AND, OR, AND NOT

= combinatory queries

!w

= case sensitive prefix query e.g.: !car or !Car

~w

= fuzzy word query e.g.: ~car or ~cra

"..."

= phrase query, performs an exact search for a single word

(...)

= brackets

c:w

= context sensitive queries e.g.: (who:Rudi Voeller)

c1,c2:w

= multi context queries e.g.: (content,who,title:Rudi Voeller)

@[... TO ...\

] = range queries e.g.: [2014-02-10 TO 2012-02-16]@

w^b

= query boosting e.g.: toList OR toAscList^1.5
