I have learned that users should know about the existence of the ES SQL dialect if they want to use ES filters inside GDAL VRT data source. This VTR works fine for me, notice the use of <SrcSQL dialect="ES"> <OGRVRTDataSource> <OGRVRTLayer name="ES_with_filter"> <SrcDataSource>ES:http://localhost:9200 allcountries</SrcDataSource> <SrcSQL dialect="ES"> { "query": { "geo_shape": { "geometry": { "shape": { "type": "envelope", "coordinates": [[14, 52],[14.1, 52.2]] } } } } } </SrcSQL> </OGRVRTLayer> </OGRVRTDataSource> -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
