Vector queries
editVector queries
editVector queries are specialized queries that work on vector fields to efficiently perform semantic search.
-
knn
query -
A query that finds the k nearest vectors to a query vector for
dense_vector
fields, as measured by a similarity metric. -
sparse_vector
query -
A query used to search
sparse_vector
field types. -
semantic
query -
A query that allows you to perform semantic search on
semantic_text
fields.
Deprecated vector queries
editThe following queries have been deprecated and will be removed in the near future.
Use the sparse_vector
query query instead.
-
text_expansion
query -
A query that allows you to perform sparse vector search on
sparse_vector
orrank_features
fields. -
weighted_tokens
query - Allows to perform text expansion queries optimizing for performance.
