Elasticsearch’s robust retrieval + the power of ChatGPT

The limitations of ChatGPT include its knowledge cutoff date, its lack of knowledge about domain-specific content, and occasional hallucinations. Meaning, ChatGPT often exacerbates when it lacks access to relevant information, which can result in incorrect answers or misleading information.

What are the limitations of ChatGPT?

To minimize the limitations of ChatGPT, you can provide ChatGPT access to specific documents relevant to your domain and questions, and enable ChatGPT’s language understanding capabilities to generate tailored responses. This can be accomplished by connecting ChatGPT to a search engine like Elasticsearch.

How to minimize the limitations of ChatGPT?

Documentation body and original URL are returned to python.

API call is made to OpenAI ChatCompletion.

Generated response is returned to python.

Python adds the original documentation source URL to the generated response and prints it to the screen for the user.

Wrap-up

 RAG is a highly efficient mechanism in natural language processing. It operates by taking a given prompt or question and retrieving relevant information from a large dataset.

What is Retriever-Augmented Generation (RAG)?

Semantic Tolerance, mirroring Recall, is a concept where the similarity function is evaluated with a broader lens, allowing for a wider range of semantic similarities between questions. This leniency can result in more matches, potentially reducing the computational load on the LLM. However, it may also lead to less precise matches.

Learn about Elasticsearch retrievers, including Standard, kNN, text_expansion, and RRF. Discover how to use retrievers with examples.

Initial types of Retrievers

How are Retrievers different, and why are they useful?

Retrievers usage examples

Standard - Search All the Text!

kNN - Search all the Dense Vectors!

text_expansion - Search all the Sparse Vectors!

rrf - Combine All the Things!

Current restrictions with Retrievers

Retrievers are a new abstraction layer added to the Search API in Elasticsearch. They offer the convenience of configuring multi-stage retrieval pipelines within a single `_search` API call.

What are retrievers in Elasticsearch?

Retrievers come with certain restrictions users should be aware of. For example, only the query element is allowed when using compound retrievers. Additionally, sub-retrievers may not use elements restricted from having a compound retriever as part of the retriever tree.

Explore the synergy between LangChain and Elasticsearch and how they are pushing the boundaries of what's possible with large language models (LLMs).

Understanding LangChain

Elasticsearch and LangChain

Elastic’s first contribution to LangChain

LangChain is a library designed to leverage the power of LLMs and combine them with other sources of computation or knowledge to create powerful applications. It is a toolbox of sorts, providing a standard interface for LLMs and facilitating their integration with other tools. LangChain makes developing applications that can answer questions over specific documents, power chatbots, and even create decision-making agents easier. All of this is done by blending LLMs with other computations (for example, the ability to perform complex maths) and knowledge bases (providing real-time inventory, for example), thus enabling the development of applications that were previously out of reach.

What is Langchain?

Elastic's ability to handle hybrid scoring adds a layer of flexibility and precision to the applications developed with LangChain. In addition to providing efficient storage and search capabilities, Elastic can also supply LLMs with vital context and can be used to store the chat history between users and LLMs. Also, with the recent contribution from Elastic, LangChain has extended its capabilities, offering developers an easier and more efficient way to generate embeddings using Elasticsearch models.
