Title: Fix for multiple negative words queries

When querying with multiple negative words, I think that the expected behaviour is to match documents without any of them, not all of them.

Example:
`dog -cat -bird` should match all documents with `dog` but without `cat`or `bird`

Currently it matches all documents with `dog` without `cat`AND `bird`
