Fields

DiskAnn	Specifies the Disk-based Approximate Nearest Neighbor algorithm, which is designed for efficiently searching for approximate nearest neighbors (ANN) in high-dimensional spaces.
Dynamic	Specifies a dynamic index that switches automatically from Flat to Hnsw indexes.
Flat	Specifies the brute force search to find the nearest neighbors.
Hnsw	Specifies the Hierarchical Navigable Small World, which performs an approximate nearest neighbor (ANN) search.
IvfFlat	Specifies an Inverted File with Flat Compression.
QuantizedFlat	Specifies an index that compresses vectors using DiskANN-based quantization methods for better efficiency in the kNN search.
