Hi everybody,

I don't know how you are using elastic search on datastore, but it's pretty
simple to search in multiple datasets. You just have to create one
different index on elastic search per dataset. It would be something like
this:

http://ckan.net/api/data/dataset1 - First dataset
http://ckan.net/api/data/dataset2 - Second dataset

When performing searches, the only thing you would have to do is to send it
to elastic search root:

curl -XPOST 'http://ckan.net/api/data/_search' -d
'{query:{"query_string":"q"}}'

This will search on all datasets for the term 'q'
