A method may include identifying, based on a first hash representation of a value, a first cache line corresponding to the value. A first bit and a second bit in the cache line may be identified as corresponding to the value based on a second hash representation of the value. The first bit may be identified based on a first offset in a binary representation of the second hash representation. The second bit may be identified based on a second offset in the binary representation of the second hash representation. Each of the first offset and the second offset may include a portion of the binary digits forming the binary representation of the second hash representation. The value may be determined to be absent from a set of values based the first bit and/or the second bit being set to a first value instead of a second value.
