MinHash retrieval by key

[DavidNemeskey]

Hi,

I see that in #233, a way was proposed to retrieve the minhash associated to a key. I can also see that it has been implemented in #234, although I cannot find the described method in 1.6.5 (only get_minhash_hashvalues; is that intentional?).

It would be great if a similar method could be added to the other LSH objects, such as the default MinHashLSH, for much of the same reasons. Thanks!

You can achieve the same effect by having a separate key-value store for key --> minhash. The LSH index itself is meant as a retrieval mechanism for minhash --> keys, not the other way around.

Still, it may be a good idea to include it as an optional feature that is turned off by default to save memory/storage. My opinion is to focus on the retrieval of minhash --> keys for now as we are not trying to build a system but an index.
