When retrieving features from a layer with PyQGIS by sth. like
feat = [f for f in my_lyr.getFeatures('"road_name" = \'myroad\'')]
feat list is empty in cases where a filter is applied that does not cover
Is there a way or a recommended workaroud to make
getFeatures() ignore an existing filter? Perhaps creating a memory layer with all features from the original layer and do the request on this memory layer?
