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


       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.


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

               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.
