NAME

Search::Indexer::Incremental::MD5::Searcher - Search your indexed files

SYNOPSIS

  my $search_string = 'find_me' ;
  my $searcher = 
	eval 
	{
	Search::Indexer::Incremental::MD5::Searcher->new
		(
		USE_POSITIONS => 1, 
		INDEX_DIRECTORY => 'text_index', 
		get_perl_word_regex_and_stop_words(),
		)
	} or croak "No full text index found! $@\n" ;
  
  my $results = $searcher->search($search_string) ;
  
  # sort in decreasing score order
  my @indexes = map { $_->[0] }
		    reverse
		        sort { $a->[1] <=> $b->[1] }
			    map { [$_, $results->[$_]{SCORE}] }
			        0 .. $#$results ;

DESCRIPTION

This module implements an incremental text indexer and searcher based on Search::Indexer.

DOCUMENTATION

Given a list of files, this module will allow you to create an indexed text database that you can later query for matches. You can also use the siim command line application installed with this module.
