Understanding the RAG method: intelligent conversational search with SmartSearchWP

On a website, search is often based on simple keywords: the surfer types in a few terms and gets a list of pages to browse.

This approach is, frankly, time-consuming and laborious when the user is looking for a precise answer. Today’s visitors expect smarter, more direct results.

Conversational search now makes it possible to ask questions in natural language and obtain instant, relevant answers. This is where RAG(Retrieval-Augmented Generation) comes in.

We’ll take a look at what the RAG method is, why it’s revolutionizing WordPress search, and how the SmartSearchWP plugin uses it to deliver intelligent answers to your visitors.

What is the RAG method?

The RAG ( Retrieval-Augmented Generation) method is a way for AI to provide more relevant answers by first fetching information from the source before responding.

In concrete terms, instead of the chatbot answering with only its general (limited or outdated) knowledge, it starts by retrieving specific information from its knowledge base – for example, the content of your website – and then uses this to generate a natural language response.

It’s like an open-book exam: the AI consults its documents (your pages) before answering, instead of relying solely on its memory.

What are the advantages of the RAG method?

Thanks to the RAG method, conversational search on your site improves the user experience:

More relevant answers: the AI bases its answers directly on your content, making them much more relevant to the question asked. No more irrelevant answers: the chatbot draws from your pages exactly the information that corresponds to the user’s query. For example, if a visitor asks a question addressed in your FAQ, the chatbot will directly provide the precise answer from that FAQ.
More reliable answers: by relying on verified content from your site, AI reduces the risk of “hallucinations” – those moments when the chatbot invents answers. If the information you’re looking for doesn’t exist on your site, SmartSearchWP will point this out instead of answering next to it. Your users have confidence in the answers they get, because they’re based on concrete facts.
Control over information sources: with RAG, you retain control over what the AI uses to respond. The chatbot’s knowledge base comes from your site and only your site, so you can update or correct it at any time. SmartSearchWP can add a link to the source page in the answer so that the user knows where the information comes from. In this way, you create transparency and avoid the need for the AI to draw on external sources.

How does SmartSearchWP use the RAG method?

SmartSearchWP applies this RAG principle transparently. First, it indexes all the pages and articles on your site (creating a knowledge base). Then, when a visitor asks a question, the plugin finds the relevant passages in this base thanks to AI ( embedding technique), and sends everything to OpenAI to generate a natural language answer. Finally, the chatbot displays this answer on your site, indicating the source if necessary. If no information is found in your content, it simply points this out.
