Descriptors and similarity search

A descriptor is a numeric vector in a descriptor set. The set defines the dimension, engines, and distance metrics used for similarity search.

Common workflow

A descriptor set exists before its descriptors are added, and each vector has the set's configured number of dimensions. FindDescriptor accepts a query vector for nearest-neighbor search and can combine similarity search with property and connection filters.

Examples. Each example includes its input and permission requirements.

Commands

• AddDescriptor
• FindDescriptor
• UpdateDescriptor

See system-defined properties for object identifiers and built-in metadata, transactions and references for command chaining, and reading results for property selection and binary output.
