Description

Changes minimum oversample factor from 0 to 1. Having an oversample factor that will return less results than the second pass needs to return will always result in less than k results being returned. This is a bug.

From a bwc perspective, we could check if index is created on 2.17 for validation. However, given this is a bug, I think its better to document it as 1.0f and not look at index versioning.
