Couchbase Lite 3.2.2 introduces support for Partial Index - Partial Value and Partial Full-Text Indexes. The Partial Index can create a smaller index, potentially improving index and query performance. You can use Partial Index to specify a WHERE clause in your index configuration. If a where clause is specified, the database will index a document only when the where clause condition is met.

You can use UNNEST in queries to unpack arrays within a document into individual rows. This capability makes it possible to join them with their parent object in the query.

You can use UNNEST within the FROM clause. You can chain UNNEST to perform multi-level UNNEST.

You can also use a new type of index, the Array Index, to allow querying with UNNEST more efficiently.

Vector Search is now available on Couchbase Lite for all platforms. Vector Search is a sophisticated data retrieval technique that focuses on matching the contextual meanings of search queries and data entries, rather than simple text matching. Vectors are represented by arrays of numbers known as embeddings, which are generated by Large Language Models (LLMs) to represent objects such as text, images, and audio. You can use Vector Search to efficiently find similar items or content based on the similarity of their vector representations. This is useful for reducing the cost per query, performing semantic or similarity search, providing recommendations among others.
