Description copied from class: `ExtendedFilter`
Returns a filter to query the columns from the clause that the initial slice filter may not have caught.

                        java.nio.ByteBuffer collectionElement)

Specified by:
  `isSatisfiedBy` in class `ExtendedFilter`
Returns:
  true if the provided data satisfies all the expressions from the clause of this filter.
