* common parameters for all vector indexes:
* `vector_dimension` - embedding vector dimensionality (should be between 1 and 16384)
* `vector_type` - vector value type (`float`, `uint8`, or `int8`)
* `vector_type` - vector value type (`float`, `uint8`, `int8`, or `bit`)
* `distance` - distance function (`cosine`, `manhattan`, or `euclidean`), mutually exclusive with `similarity`
* `similarity` - similarity function (`inner_product` or `cosine`), mutually exclusive with `distance`
* specific parameters for `vector_kmeans_tree` (see [the reference](../../../../dev/vector-indexes.md#kmeans-tree-type)):
