Note: nprobes is only applicable if an ANN index is present. If specified on a table without an ANN index, it is ignored. - **refine_factor** (default: None): Refine the results by reading extra elements and re-ranking them in memory.
- A higher number makes search more accurate but also slower. If you find the recall is less than idea, try refine_factor=10 to start.
+ A higher number makes search more accurate but also slower. If you find the recall is less than ideal, try refine_factor=10 to start.
e.g., for 1M vectors divided into 256 partitions, if you're looking for top 20, then refine_factor=200 reranks the whole partition.
