$tablename Name of the table (string)
$searchtype is string Can be "start_with" or "exact"
+This query builder is very limited, it should be replaced with DBIx::Class

+support filters of type
+
+ ( f1 = a OR f2 = a ) AND fx = b AND fy = c
+
+Call for the query above is:

+NOTE: Current implementation may remove parts of the iinput hashrefs. If that is a problem
+a copy needs to be created in _filter_fields() below
