A collection of metadata key-value pairs to filter the search results. Only entries that match these pairs are returned.

options VectorRetrievalOptions

A combination of VectorRetrievalOptions flags indicating which parts of each matching entry (vector data, metadata, or both) are included in the returned PointEntry.

maxResults uint

The maximum number of entries to return. Use this to limit memory usage and response time when querying large collections.

cancellationToken CancellationToken

An optional token that can be used to cancel the asynchronous retrieval operation.

Returns

Task<List<PointEntry>>
