NAME
       KinoSearch::Search::Matcher - Match a set of document ids.

SYNOPSIS
	   # abstract base class

DESCRIPTION
       A Matcher iterates over a set of ascending document ids.	 Some Matchers
       implement score() and can assign relevance scores to the docs that they
       match.  Other implementations may be match-only.

CONSTRUCTORS
   new()
	   my $matcher = MyMatcher->SUPER::new;

       Abstract constructor.

ABSTRACT METHODS
   next()
       Proceed to the next doc id.

       Returns: A positive doc id, or 0 once the iterator is exhausted.

   get_doc_id()
       Return the current doc id.  Valid only after a successful call to
       next() or advance() and must not be called otherwise.

   score()
       Return the score of the current document.

       Only Matchers which are used for scored search need implement score().

METHODS
   advance(target)
       Advance the iterator to the first doc id greater than or equal to
       "target". The default implementation simply calls next() over and over,
       but subclasses have the option of doing something more efficient.

       ·   target - A positive doc id, which must be greater than the current
	   doc id once the iterator has been initialized.

       Returns: A positive doc id, or 0 once the iterator is exhausted.

INHERITANCE
       KinoSearch::Search::Matcher isa KinoSearch::Object::Obj.
