Search-QueryParser version 1.0
==============================

This module parses a query string into a data structure to be handled
by external search engines.  For examples of such engines, see
File::Tabular and Search::Indexer.

The query string can contain simple terms, "exact phrases", field
names and comparison operators, '+/-' prefixes, parentheses, and
boolean connectors.

The parser can be parameterized by regular expressions for specific
notions of "term", "field name" or "operator" ; see the "new"
method. The parser has no support for lemmatization or other term
transformations : these should be done externally, before passing the
query data structure to the search engine.

The data structure resulting from a parsed query is a tree of terms
and operators, as described in the "parse" method.  The interpretation
of the structure is up to the external search engine that will receive
the parsed query ; the present module does not make any assumption
about what it means to be "equal" or to "contain" a term.
