AI search transforms how readers interact with your knowledge base. Instead of requiring readers to guess the right keywords, Nulix AI search understands the intent behind a question and returns a direct excerpt from the most relevant article — making your content genuinely conversational and easier to navigate. Standard keyword search looks for exact or near-exact word matches between a query and your article content. AI search goes further by understanding the meaning of a question, not just its words. This means a reader can type a full question in plain language and get a pinpointed answer — even if the exact phrase never appears in your article. AI search is available on the Pro plan and above. Once your workspace is on an eligible plan, enable it for any knowledge base in a few steps.
1

Open Settings

In the Nulix sidebar, click Settings and select the knowledge base where you want to enable AI search.
2

Navigate to the Search tab

Click the Search tab in the knowledge base settings panel.
3

Enable AI Search

Toggle Enable AI Search to the on position and click Save Changes. Nulix will begin indexing your articles for semantic search immediately.
Initial indexing for AI search may take a few minutes for large knowledge bases. Readers will see standard keyword results in the meantime, with no downtime or disruption.

​
How It Works

When you enable AI search, Nulix processes your published articles and builds a semantic index — a representation of the meaning of each section of your content. When a reader submits a query, Nulix compares the meaning of their question against this index to find the best-matching passage, then surfaces that passage as a direct answer above the standard results list.

​
Example

A reader searches:
“how do I reset my password”
Even if your article is titled “Account Security” and uses the phrase “change your credentials” instead of “reset your password,” AI search recognises that these describe the same action and returns the relevant paragraph directly.
Data privacy: Nulix processes your article content to build and maintain the semantic search index. This content is never used to train external AI models or shared outside your workspace. Indexing happens within Nulix’s secure infrastructure. For full details, see the Nulix Privacy Policy.
Longer, well-structured articles with clear headings give AI search more context to work with and significantly improve accuracy. Break articles into logical sections with descriptive H2 and H3 headings rather than writing one long block of text.
