Abstract: Techniques are disclosed pertaining to layered filtering. A computer system may store records in a hierarchy of levels. The computer system may receive a request to perform a key range search to locate records that fall within a key range and satisfy selection criteria. The computer system may perform the key range search. As part of processing a particular level, the computer system may receive a first set of records associated with another level and select a second set of records from the particular level that fall within the key range and satisfy the selection criteria. The computer system may merge the first and second sets of records into a third set of records, which may include not inserting, into the third set, any record of the first set of records for which there is a newer version in the particular level that does not satisfy the selection criteria.
