Abstract
In some embodiments, a system transforms an initial user query into a first rewritten query using a first query rewriting algorithm, executes a search of a data repository using the first rewritten query to generate a set of results, executes a chunking process on the set of results to generate chunks of data, transforms the initial user query into a second rewritten query using a second query rewriting algorithm, generates corresponding embeddings for the second rewritten query and the chunks of data using a reranking model, selects a subset of the chunks of data based on a comparison of the embeddings for the chunks of data and the embedding for the initial user query, generates a prompt based on the initial user query and the subset of the chunks of data, submits the prompt to a Large Language Model (LLM) to generate a response to the initial user query.
