I thought about passing in Bits but I don't think it will work because 
searchLeaf is at the segment level so we'd need segment level Bits.

We could pass in a Query and collect the segment level bits. Would be easy to 
implement as well. 

KnnVectorQuery(String field, float[] target, int k, Query query)
