   Let's make the situation more clear. In my consideration, I have a bloom 
filter (just call it b) which comprised of the merge of several thousand (lets 
say 10,000) filters. And this is already done and I really care about the query 
performance. The query is like this:
   Given an object, check whether it in b.
   In my opinion, there is no need to build a new bloom filter for every object 
and compare it with b. We only need to check current object's hash location in 
b is 1.
