NAME

Metadata::DB::Search - search the indexed metadata

SYNOPSIS

   use Metadata::DB::Search;
   use Metadata::DB;
   
   my $s = Metadata::DB::Search->new({ DBH => $dbh });

   $s->search({
      'age:exact'       => 24,
      'first_name:like' => 'jo',   
      'speed:morethan'  => 40,
   });

   $s->ids_count or die('nothing found');

   for(@$ids) {
      my $o = new Metadata::DB({ DBH => $dbh, id => $_ });   
   
   }

EXAMPLE 2

   my $s = Metadata::DB::Search->new({ DBH => $dbh });
   
   $s->search_params_add( age => 24 );
   
   $s->search_params_add( 'first_name:like' =>'jo' );
   
   $s->search;

   my @matching_ids = @{ $s->ids };

   for my $id ( @matching_ids ){
   
      
   }
