Query a Vector Search Index

Query a Vector Search Index

Usage

db_vs_indexes_query(
  index,
  columns,
  filters_json,
  query_vector = NULL,
  query_text = NULL,
  score_threshold = 0,
  query_type = c("ANN", "HYBRID"),
  num_results = 10,
  host = db_host(),
  token = db_token(),
  perform_request = TRUE
)

Arguments

index

Name of vector search index

columns

Column names to include in response

filters_json

JSON string representing query filters, see details.

query_vector

Numeric vector. Required for direct vector access index and delta sync index using self managed vectors.

query_text

Required for delta sync index using model endpoint.

score_threshold

Numeric score threshold for the approximate nearest neighbour (ANN) search. Defaults to 0.0.

query_type

One of ANN (default) or HYBRID

num_results

Number of returns to return (default: 10).

host

Databricks workspace URL, defaults to calling db_host().

token

Databricks workspace token, defaults to calling db_token().

perform_request

If TRUE (default) the request is performed, if FALSE the httr2 request is returned without being performed.

Details

You cannot specify both query_vector and query_text at the same time.

filter_jsons examples:

• '{"id <": 5}': Filter for id less than 5

• '{"id >": 5}': Filter for id greater than 5

• '{"id <=": 5}': Filter for id less than equal to 5

• '{"id >=": 5}': Filter for id greater than equal to 5

• '{"id": 5}': Filter for id equal to 5

• '{"id": 5, "age >=": 18}': Filter for id equal to 5 and age greater than equal to 18

filter_jsons will convert attempt to use jsonlite::toJSON on any non character vectors.

Refer to docs for Vector Search.
