Let's say we have tons of documents with vector such as {a:1.0, b:1.2, ...}  
for each.  
and what I want to do is to query with a user side vector, maybe {b:9.2,  
c:1.2, ...}, and return documents with highest dot-product values.

I am totally a newbie to lucene/elasticsearch, can anyone tell me is it  
possible to achieve this with ES?

thanks,
