I save 100.000 Vectors of inside a database. Each vector includes a dimension 60. (int vector[60])

I Quickly take one and wish present vectors towards the user so as of lowering resemblance of the selected one.

I personally use Tanimoto Classifier to check 2 vectors:

Can there be any techniques to prevent doing through all records within the database?

Yet another factor! I don't have to sort all vectors within the database. I whant to obtain top 20 probably the most similar vectors. So perhaps we are able to roughly threshold 60% of records and employ the relaxation for sorting. What is your opinion?
