## IVF_FLAT
**IVF** (*Inverted File*) is an index type based on quantization. It divides the points in space into `nlist` units by the clustering method. During searching vectors, it compares the distances between the target vector and the center of all the units, and then selects the `nprobe` nearest unit. Afterwards, it compares all the vectors in these selected cells to get the final result.

IVF_FLAT is the most basic IVF index, and the encoded data stored in each unit is consistent with the original data.
