Bloomfilter needs to load from filesystem, it may costs time and space. If
we can exactly determine the existence/nonexistence of the value from other
filters , then we can avoid using Bloomfilter to Improve performance.
When the minMax values in StatisticsFilter is same, we can exactly
determine the existence/nonexistence of the value.
When we have page dictionaries, we can also determine the
existence/nonexistence of the value.
