      Description

      During automatic use of indexes, we analyze the query predicate to pull out what we can use the index on. Not all of the predicate can necessarily be processed with a single index. Currently, we return the residual predicate from the IndexHandler but do not process it further. We run the full original predicate on the index table. Ideally, we would want to only run the residual predicate so we don't have to do as much processing.
