Welcome to the Chat with your data Solution accelerator repository! The Chat with your data Solution accelerator is a powerful tool that combines the capabilities of Azure AI Search and Large Language Models (LLMs) to create a conversational search experience. This solution accelerator uses an Azure OpenAI GPT model and an Azure AI Search index generated from your data, which is integrated into a web application to provide a natural language interface, including speech-to-text functionality, for search queries. Users can drag and drop files, point to storage, and take care of technical setup to transform documents. There is a web app that users can create in their own subscription with security and authentication.
This repository provides a template for setting up the solution accelerator, along with detailed instructions on how to use and customize it to fit your specific needs. It provides the following features:
- Chat with an Azure OpenAI model using your own data
- Upload and process your documents
- Index public web pages
- Easy prompt configuration
- Multiple chunking strategies
If you need to customize your scenario beyond what Azure OpenAI on your data offers out-of-the-box, use this repository. If you don't require customizations, use Azure Machine Learning prompt flow.
The accelerator presented here provides several options, for example:
- The ability to ground a model using both data and public web pages
- Advanced prompt engineering capabilities
- An admin site for ingesting/inspecting/configuring your dataset on the fly
- Running a Retrieval Augmented Generation (RAG) solution locally, as a Docker container

This accelerator also works across industry and roles and would be suitable for any employee who would like to get quick answers with a ChatGPT experience against their internal unstructured company data.
Tech administrators can use this accelerator to give their colleagues easy access to internal unstructured company data. Admins can customize the system configurator to tailor responses for the intended audience.
The sample data illustrates how this accelerator could be used in the financial services industry (FSI).
In this scenario, a financial advisor is preparing for a meeting with a potential client who has expressed interest in Woodgrove Investments’ Emerging Markets Funds. The advisor prepares for the meeting by refreshing their understanding of the emerging markets fund's overall goals and the associated risks.
Now that the financial advisor is more informed about Woodgrove’s Emerging Markets Funds, they're better equipped to respond to questions about this fund from their client.
Note: Some of the sample data included with this accelerator was generated using AI and is for illustrative purposes only.
Many users are used to the convenience of speech-to-text functionality in their consumer products. With hybrid work increasing, speech-to-text supports a more flexible way for users to chat with their data, whether they’re at their computer or on the go with their mobile device. The speech-to-text capability is combined with NLP capabilities to extract intent and context from spoken language, allowing the chatbot to understand and respond to user requests more intelligently.

Access to documents
Only upload data that can be accessed by any user of the application. Anyone who uses the application should also have clearance for any data that is uploaded to the application.
Depth of responses
The more limited the data set, the broader the questions should be. If the data in the repo is limited, the depth of information in the LLM response you can get with follow up questions may be limited. For more depth in your response, increase the data available for the LLM to access.
Response consistency
Consider tuning the configuration of prompts to the level of precision required. The more precision desired, the harder it may be to generate a response.
Numerical queries
The accelerator is optimized to summarize unstructured data, such as PDFs or text files. The ChatGPT 3.5 Turbo model used by the accelerator is not currently optimized to handle queries about specific numerical data. The ChatGPT 4 model may be better able to handle numerical queries.
Use your own judgement
AI-generated content may be incorrect and should be reviewed before usage.
Azure AI Search used as retriever in RAG
Azure AI Search, when used as a retriever in the Retrieval-Augmented Generation (RAG) pattern, plays a key role in fetching relevant information from a large corpus of data. The RAG pattern involves two key steps: retrieval of documents and generation of responses. Azure AI Search, in the retrieval phase, filters and ranks the most relevant documents from the dataset based on a given query.
The importance of optimizing data in the index for relevance lies in the fact that the quality of retrieved documents directly impacts the generation phase. The more relevant the retrieved documents are, the more accurate and pertinent the generated responses will be.
Azure AI Search allows for fine-tuning the relevance of search results through features such as scoring profiles, which assign weights to different fields, Lucene's powerful full-text search capabilities, vector search for similarity search, multi-modal search, recommendations, hybrid search and semantic search to use AI from Microsoft to rescore search results and moving results that have more semantic relevance to the top of the list. By leveraging these features, one can ensure that the most relevant documents are retrieved first, thereby improving the overall effectiveness of the RAG pattern.
Moreover, optimizing the data in the index also enhances the efficiency, the speed of the retrieval process and increases relevance which is an integral part of the RAG pattern.
Azure AI Search
- Consider switching security keys and using RBAC instead for authentication.
- Consider setting up a firewall, private endpoints for inbound connections and shared private links for built-in pull indexers.
- For the best results, prepare your index data and consider analyzers.
- Analyze your resource capacity needs.
Before deploying Azure RAG implementations to production
- Follow the best practices described in Azure Well-Architected-Framework.
- Understand the Retrieval Augmented Generation (RAG) in Azure AI Search.
- Understand the functionality and configuration that would adapt better to your solution and test with your own data for optimal retrieval.
- Experiment with different options, define the prompts that are optimal for your needs and find ways to implement functionality tailored to your business needs with this demo, so you can then adapt to the accelerator.
- Follow the Responsible AI best practices.
- Understand the levels of access of your users and application.
Chunking: Importance for RAG and strategies implemented as part of this repo
Chunking is essential for managing large data sets, optimizing relevance, preserving context, integrating workflows, and enhancing the user experience. See How to chunk documents for more information.
These are the chunking strategy options you can choose from:
- Layout: An AI approach to determine a good chunking strategy.
- Page: This strategy involves breaking down long documents into pages.
- Fixed-Size Overlap: This strategy involves defining a fixed size that’s sufficient for semantically meaningful paragraphs (for example, 250 words) and allows for some overlap (for example, 10-25% of the content). This usually helps creating good inputs for embedding vector models. Overlapping a small amount of text between chunks can help preserve the semantic context.
- Paragraph: This strategy allows breaking down a difficult text into more manageable pieces and rewrite these “chunks” with a summarization of all of them.
