Peter's comments on Mifluz are very accurate.

Mifluz uses zlib and some bit compression. Coupled with

Just a little clarification on this point. Mifluz provides
two kind of compression : zlib (1/2) and custom (1/8). The first
scheme (using zlib) achieves 1/2 compression on the index and could
be used outside mifluz (patch to Berkeley DB). The second scheme
is only fit for a mifluz inverted index and since it knows the internal
structure of the key, it is able to compress to 1/8.
