Index concepts¶

Short when to use primers plus pointers to zvec.org. First-party math, citations, and SDK defaults live under Theory.

Index types in ZVec.NET¶

Index	Use case	SDK type	Platform notes
HNSW	General-purpose ANN	`ZVecHnswIndexParam`	All supported RIDs
Flat	Exact search (small datasets)	`ZVecFlatIndexParam`	All supported RIDs
IVF	Clustered ANN	`ZVecIvfIndexParam`	All supported RIDs
HNSW-RaBitQ	Quantized HNSW	`ZVecHnswRabitqIndexParam`	x86_64 + AVX2 only; C API create still blocked — see coverage
DiskANN	Disk-based ANN	`ZVecDiskAnnIndexParam`	Linux only
Vamana	Graph-based ANN	`ZVecVamanaIndexParam`	All supported RIDs
