• You can now use the ai.hybrid_search() function, which fuses results from each search type into a single list using the Reciprocal Rank Fusion (RRF) algorithm. For more information, see Run hybrid vector similarity search. • AlloyDB supports the rum extension for complex full-text search operations. The rum extension extends standard GIN indexes by storing positional information directly in the index. This enables faster phrase searches and relevance ranking without needing to access the table data. For more information, see Create and manage a RUM index.
