[ckan-dev] Spatial search for datasets with dataset collection

Mon Aug 5 19:08:59 UTC 2013

Thank you very much, Adrià.   The POST requirement and the fq format are what was causing me problems.  
I am now able to geographically query collections just fine.
Thanks,

> "extras":{"ext_bbox":"-121,45,-120,46"}}'
> http://catalog.data.gov/api/action/package_search
