Oh fine. Caution point was useful for me.
Yes I wanted to do something similar to filer queries. It is not XY
problem. I am simply trying to implement something as described below.
I have a [non-clinical] group sets in system and I want to build bitset
based on the documents belonging to that group and save it.
So that, While searching I want to retrieve similar bitset from Solr engine
for matched document and then execute logical XOR. [Am I clear with problem
explanation now?]
So what I am looking for is, If I have to retrieve bitset instance from
Solr search engine for the documents matched, how can I get it?
And How do I save bit mapping for the documents belonging to a particular
group. thus enable XOR operation.
Thanks - David
