Hi, A negative boost does not exist and a very low boost is still a boost. In queries, you can work around the problem by giving a very high boost do documents that do not match; the negation parameter with a high boost will do the trick.
If you don't want to index certain documents then you'll need an indexing filter. That's a different approach.
