Querying Our Data, Part 1 – Context Retrieval

The focus of this chapter will be on understanding the querying capabilities of LlamaIndex in an RAG workflow. We’ll be covering the overall working of the querying system, mostly focusing on the retrieval capabilities of the framework.

Here are the main sections that will be covered in this chapter:

Learning about query mechanics – an overview
Understanding the basic retrievers
Building more advanced retrieval mechanisms
Increasing efficiency with asynchronous retrieval
Working with metadata filters, tools, and selectors
Transforming queries and generating sub-queries
Understanding the concepts of dense and sparse retrieval
