Hi, In fact the $or native operator is disabled on Geotools MongoDB module. This is because MongoDB until 2.4.9 version don't support the mix of $or and spatial indexes very well.
Checking some MongoDB release notes seems like this was improved on 2.6 version: $or and GeoSpatial Queries Changed in version 2.6 $or supports geospatial clauses with the following exception for the near clause (near clause includes $nearSphere and $near). $or cannot contain a near clause with any other clause. So if Geotools MongoDB module starts to support native $or clause by default this could lead to some bugs on previous versions. A good improvement could be a configuration for activating/deactivating native $or. Regards, Fernando Mino == GeoServer Professional Services from the experts!

And OR operation by itself requesting all records from collection. But with attributes that are multiple something goes wrong. I think it's a bug. If you have any sugestions please tell me. -- Sent from: http://osgeo-org.1560.x6.nabble.com/GeoServer-Dev-f3819232.html _______________________________________________ Geoserver-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/geoserver-devel
