Search::Tools is a set of utilities for building search applications.
Rather than adhering to a particular search application or framework, the
goal of Search::Tools is to provide general-purpose methods for common
search application features. Think of Search::Tools like a toolbox rather
than a hammer.

Examples include:
* Parsing search queries for the meaningful terms
* Rich regular expressions for locating terms in the original indexed
documents
* Contextual snippets showing query terms
* Highlighting of terms in context
* Spell check terms and suggestions of alternate spellings.

Search::Tools is derived from some of the features in HTML::HiLiter and
SWISH::HiLiter, but has been re-written with an eye to accomodating more
general purpose features.
