Preparing for RAG-enhanced search with ELSER and RRF
In our continued discussion on semantic search and its various facets, we now turn our attention to the integration of RAG-enhanced search with ELSER and RRF.
Before we dive into the details of the integration of RAG, ELSER, and RRF, it’s essential to appreciate the journey and evolution of search methodologies that brought us here.
The journey started with lexical search. This simple yet powerful methodology, which involves matching exact terms, was vastly adopted and capable of delivering reliable results. It laid the foundation for what was to come.
The next leap forward came with the introduction of vector search, adding a new dimension to our understanding of search queries. This technique enabled systems to comprehend the “meaning” or semantic content behind queries, far beyond the capabilities of a basic lexical search.
Elastic RRF further boosted the relevancy of results. This technique cleverly...
