...ee the announcement blog post and the “What's New in the Vector Similarity Search Extension?” post . Usage To create a new HNSW (Hierarchical Navigable Small Worlds) index on a table with an ARRAY column, use the CREATE INDEX statement with the USING...HNSW clause. For example: INSTALL vss ; LOAD vss ; CREATE TABLE my_vector_table ( vec FLOAT [ 3 ]); INSERT INTO my_vector_table..._value ( a , b , c ) FROM range ( 1 , 10 ) ra ( a ), range ( 1 , 10 ) rb ( b ), range ( 1 , 10 ) rc ( c ); CREATE INDEX my_hnsw_index ON my_vector_table USING HNSW ( vec ); The index will then be used to accelerate queries that use an ORDER BY clause... - https://man.mtool.work/duckdb/1.3/core_extensions/vss.html
