NAME

       Plucene::Search::Searcher - base class for searchers

DESCRIPTION

       Abstract base class for searchers.

       Searching is the operation of locating a subset of the documents that contains desired content or that
       their attributes match some specification.

       The input for a search operation is a 'query' that specifies a criteria for selecting the documents and
       its output is a list of documents ('hits') that matched that criteria.

       The hit list is typically ordered by some measure of relevancy (called 'ranking' or 'scoring') and may
       contain only a subset of the set of documents that matched the query (typically the ones with the highest
       scored documents).

       The search operation is performed on an 'index' which is a specialized database that contains a pre
       compiled information of the document set.  The index database is optimized for locating quickly documents
       that contains certain words or terms.

METHODS

   search
               my Plucene::Search::Hits $hits = $searcher->new($query, $filter);

       This will return the Plucene::Search::Hits object for the passed in query and filter. At this stage,
       filter is optional.
