Mike Adamson updated CASSANDRA-18715:
-------------------------------------
Summary: Add support for vector search in SAi (was: Add support for ORDER
BY <column> ANN OF <vector>)
> Add support for vector search in SAi
> ------------------------------------
>
> Key: CASSANDRA-18715
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18715
> Project: Cassandra
> Issue Type: Improvement
> Components: Feature/Vector Search
> Reporter: Mike Adamson
> Priority: Normal
>
> Approximate nearest neighbour search results are scored. As such, it is
> important that the results are returned in score order. In order to do this
> proposal is that the ANN search is expressed in the grammar as:
> {code:java}
> ORDER BY <column> ANN OF <vector>{code}
> rather than including the ANN search in the where clause.
