Conventional search systems rely on exact matches on properties like keywords, tags, or other metadata, lexical similarity, or the frequency of word occurrences. Recently, vector similarity search has transformed the search process. It leverages machine learning to capture the meaning...
Executes a test function on each item in the Vector and returns a new Vector containing all items that returntruefor the specified function. If an item returnsfalse, it is not included in the result Vector. The base type of the return Vector matches the base type of the Vector on which ...
When searchable content is represented as vectors, a query can find close matches in similar content. The embedding model used for vector generation knows which words and concepts are similar, and it places the resulting vectors close together in the embedding space. For example, vectorized source...

Semantic understanding: Rather than searching for exact matches, vector search enables semantic searching. This means that even if the query words aren't present in the index, but the meanings of the phrases are similar, they will still be considered a match. ...

In the vector-only query, which uses HNSW for finding matches, the Sublime Cliff Hotel drops to fourth position. Historic Lion, which was second in the full-text search and third in the vector search, doesn't experience the same range of fluctuation, so it appears as a top match in a ...
Get the exhaustive property: When true, triggers an exhaustive k-nearest neighbor search across all vectors within the vector index. Useful for scenarios where exact matches are critical, such as determining ground truth values. Returns: the exhaustive value. ...
