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
   doc_freq / max_doc / doc / _search_hc search_top
       These must be defined in a subclas

   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.
