One way to do it might be to use the Solr 'nested query' functionality.

Not entirely sure this will work exactly as I've written it, but give
you some ideas of what nested query can do. Note not fully URL-encoded
for clarity:
&defType=lucene&q= _query_:"{!edismax qf='p,q,r' fq='field1:xyz'}abc
def" AND _query_:"{!edismax mm=100% qf='q, r, s'}jlk"

Hi,
I am using Solr 3.1 with edismax. My frontend allows the user to create
arbitrarily complex queries by modifying q, fq, qf and mm (only 1 and 100% are
allowed) parameters. The queries can then be saved by the user.
The user should be able to perform set operations on the saved searches. For
example, the user may want to see all documents which are returned both by
saved search 1 and saved search 2 (equivalent to intersection of the two).
If the saved searches contain q, fq and/or mm, then I can combine the saved
searches to create a new query which will be equivalent to their intersection.
However, I can't figure out how to handle qf?
For example,
Query 1 = q=abc def&fq=field1:xyz&mm=1&qf=p,q,r
Query 2 = q=jkl&mm=100%&qf=q,r,s
How do I get the list of common documents which are present in the result set
of both queries?
Thanks,
Nikhil
