Hybrid search is an advanced information retrieval technique that lets you search documents by keywords and vectors, to achieve more relevant search results.

• Understand Hybrid Search
  With hybrid search, you can search through your documents by performing a combination of full-text queries and vector-based similarity queries, using out-of-the-box or custom scoring techniques.
• Query Hybrid Vector Indexes End-to-End Example
  In this example, you can see an end-to-end hybrid search workflow. First, you run the CREATE HYBRID VECTOR INDEX SQL statement that prepares, chunks, embeds, stores, and indexes your input data. You then perform vector search alongside keyword search using the DBMS_HYBRID_VECTOR.SEARCH PL/SQL query API.
