man Plucene::Search::Searcher () - base class for searchers
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.
