Indexing objects in a datastore, where the objects are characterized by a set of object properties. For objects from a datastore: a Bloom filter for the object properties, based on a predetermined Bloom filter configuration, is created; the Hamming value of the Bloom filter is determined; a binary logarithm of the Bloom filter is calculated; and the Bloom filter, the Hamming value, the binary logarithm, and a representation of the object is stored in the datastore.
