Hi,

Is it possible to get access to terms information that is indexed in ES and  
run some kind of map-reduce on them using ES-Hadoop? For example, let's say  
I have a CSV data set that was indexed into ES, with one particular field  
that was setup to be analyzed using a snowball analyzer. So, can I read the  
terms that were generated due to the snowball analyzer using ES-Hadoop?  
Something similar to how the ES scripts give access to TF, TTF, etc.

Also, is it possible to get the generated ID for an ES document using the  
ES-Hadoop APIs? This way, I could be able to query a document's term vector  
by \_id, and maybe do calculations on terms, one document at a time.

Regards,  
Aritra
