It's a good idea to do multiple pruning at one time, but it also has
shortcomings.
1. The datamap has to deal with the AND/OR logic of the composite
expressions. If the expressions are AND, it needs to do intersection of the
pruned result; If the expressions are OR, it needs to do union of the pruned
result. It will makes the datamap complicated to handle.
2. Besides, you can see it from the maillist that, current expressions
forwarded to BloomDataMap contains too much unwanted expressions.
