Description

This enhances the wfsGeoCoder in querypanel's spatial field to use cross layer filtering.
If this option is configured, the querybuilder will show the geometry as usual, but the effective filter will be generated using "cross layer filtering" instead of the geometry.
This improve both performances and reduces the size of the filter, that can be used also as cql_filter in URL without exceeding max URL length.
