-=head2 cache
-
-Set to 1 to cache search results. This prevents extra SQL queries if you
-revisit rows in your ResultSet:
-
- my $resultset = $schema->resultset('Artist')->search( undef, { cache => 1 } );
-
- while( my $artist = $resultset->next ) {
- ... do stuff ...
- }
-
- $rs->first; # without cache, this would issue a query
-
-By default, searches are not cached.
-
