Building a Retrieval-Augmented Generation (RAG) Solution
Retrieval-Augmented Generation (RAG) is a powerful technique that combines the strengths of large language models (LLMs) and information retrieval to generate more accurate, relevant, and informative responses. By leveraging a knowledge base, RAG systems can access and process relevant information, ensuring that the generated content is grounded in factual data.
– Gather diverse data sources (text, images, audio, video)
– Preprocess data (cleaning, deduplication, PII handling)
Data Cleaning: Clean and preprocess the data to remove noise, inconsistencies, and irrelevant information.
Data Chunking: Break down large documents into smaller, manageable chunks. This can be done based on semantic meaning, paragraph boundaries, or fixed-size chunks.
– Implement multimodal chunking strategies
– Select or fine-tune embedding models for different modalities
– Generate embeddings for all data types
– Experiment with domain-specific embedding models

RAG: What is it?
RAG is a new method of natural language processing (NLP) that combines the accuracy of information retrieval systems with the strength of large language models (LLMs). Text, code, photos, and even sounds are among the vast amounts of content used to train RAG models. They frequently make use of pre-existing general LLMs from Amazon, Microsoft / OpenAI, Google, or Meta. However, they also have access to an outside knowledge base, which enables them to produce more precise and instructive answers.
How does vector search relate to RAG, and what is it?
A strong method for locating related things in big datasets, particularly unstructured data like text, photos, and audio, is vector search. It captures the context and meaning of the material using mathematical vectors rather than keywords. Our blog, Vector Search vs. Keyword Search, has further information.
RAG is essentially a vector search use case. A key component of the Retrieval-Augmented Generation (RAG) architecture is vector search. It serves as the information retrieval engine that powers the large language model (LLM), which is in charge of producing answers.
Our comprehensive blog post describing Retrieval Augmented Generation has additional information about the RAG architecture and the use of vector search.
Why use RAG?
To put it simply, RAG is an architecture that uses artificial intelligence (AI) to let people search and respond to queries based on your content. Additionally, it lessens the possibility of “hallucinations,” in which generative AI generates unwanted or inaccurate responses to queries that are submitted.
This is essential for assisting you in maintaining control and providing your users with the ideal experience, whether you are running search on an e-commerce website, support portal, or specialist knowledge application. RAG also enables you to develop a new conversational search paradigm that can be implemented in mobile applications, chatbots, support assistants, and search bards.
Will Keyword Search be replaced by RAG?
The short answer is no. Many customers will still choose a hybrid search solution that uses both AI and conventional keyword search, even though some applications would be appropriate for a pure RAG implementation. The capability to pose sophisticated queries, such as “which running shoes are the best-selling?However, they will also want to enter more conventional search keywords, such as “black Nike running shoes.”
Advantages of Using Hybrid Search and RAG
In addition to the apparent advantage of providing consumers with responses based solely on your content, your applications can provide:
More precise and pertinent results: RAG and Hybrid Search focus on what consumers need, comprehending the context and subtleties of their inquiries, saving time spent sorting through pointless links and lowering the possibility of “hallucinations.”
Personalized insights: Receive information based on the interests and needs of a particular user.RAG can provide customized information by taking into account your users’ preferences and prior knowledge by using their query history.
Increased productivity: Make use of generative models’ potential.RAG can use the information it has acquired to produce entertaining and natural-sounding summaries of original content or even responses to in-depth queries.
Better data integration: Easily include domain-specific or private information in your search.Other sources that are not available to conventional search engines can be accessed and utilized by RAG.
Increased auditability and transparency: Recognize where your information comes from.RAG promotes confidence and trust by enabling you to track the retrieved documents that were utilized to produce your results.
The difficulties and dangers of retrieval augmented generation
Although using RAG and hybrid search has many exciting advantages, there are drawbacks to take into account.
Even while it could appear that AI diminishes the significance of dictionaries, ontologies, and metadata, content processing is still crucial because neglecting them can result in inaccurate search results and responses. Additionally, introducing inappropriate content can make the “hallucination” issue worse rather than better.
Performance and cost can be affected by LLMs: As a third party added to your architecture, LLMs may cause unforeseen performance problems and raise your search application’s operating expenses.
The implementation of hybrid search with RAG still necessitates specialist search knowledge, such as managing search indexes, building searchable vector databases, and designing user interfaces (UIs) that can incorporate faceting and other capabilities in addition to a basic chat-like interface.
Our blog post, “5 Common Challenges Implementing Retrieval Augmented Generation” (RAG), has considerably additional information.
Through trial and error, RAG can be implemented numerous times. or withNextbrick once.
Early on, using AI to create innovative search solutions can seem deceptively amusing. Do you recall the “plug-and-play” claims made by early search vendors? Even while open-source solutions like Elasticsearch and Solr provide flexibility, overcoming the challenges of AI search to attain enterprise-grade security, performance, and scalability is still quite difficult.
