i want to implement index as tree with bloom filter using locality sensitive hashing.
I am not sure it can help, but maybe there is something implemented in Lucene
https://lucene.apache.org

MG4J uses Bloom Filter: http://mg4j.di.unimi.it/
From the documentation: "Optionally, an index cluster may provide Bloom filters to reduce useless access to local indices that do not contain a term."

This is link for Bloom filter example with Java implementation:
