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.
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.
