Why do we need AI-powered Search?
As your course library grows, so does the amount of valuable knowledge buried inside it: policies, handbooks, process training, compliance material. But knowledge that can't be found when it's needed is knowledge that doesn't get used.
Until now, search in Learnster U only matched on course and resource titles, if a learner didn't know the exact words a course was named, their only option was to browse page by page, or ask someone else.
AI-powered search changes that. Learners can now ask a question in their own words, for example, "how do I handle a customer refund?" and get pointed straight to the answer inside the course content they already have access to, without needing to know which course it's in, or even that it exists.
This is what turns a course from something a learner completes once and moves on from, into a knowledge base they actually come back to, when they're handling a real situation, making a decision, or just need a reminder of how something works. Making this available for your learners is one of the most direct ways to make the content you've already built in Learnster genuinely useful, day to day.

How it works
AI-powered Search is available through the search bar in Learnster U.
Learners can type a question or describe what they're looking for in their own words. AI interprets the meaning behind the question and matches it to the excerpts of course content whose context fits best- so results stay relevant even when the exact search wording doesn't match
AI search results so called "Context matches" show short excerpts from the matching content, along with the course they belong to, so learners can find the information they are looking for directly from the search result modal
Learners can also jump straight to the relevant spot in the course page from the search result, to quickly find the context of search result.
Search results always respect existing course permissions- learners only ever see content from courses they have access to.
👇AI-powered Search results, called "Context matches", show the most relevant content excerpts. Find answers directly in excerpts or jump to the exact course page in one click.
How AI-powered Search finds the right information
AI- Search results, labeled as "Context matches" are powered by a technique called RAG (Retrieval-Augmented Generation). Here is a simplified version of how it works:
AI indexes your entire course library, splitting the content into smaller excerpts and analyzing each one to understand what it's actually about.
When a learner types a search query, AI interprets the meaning behind their question — not just the words they used — and compares it against those indexed excerpts to find the ones that match best.
The AI layer allows users to type search queries that are not purely keyword based, instead learners can describe what they are looking for or ask questions- AI will understand!
The best-matching excerpts are what show up as Context matches, each linked straight back to the right course and page.
Right now, indexing covers text-based course content only — course pages, descriptions, and syllabi. We're already looking into extending this to other content types, such as resources, video transcripts, and PDFs, so more of your content becomes searchable over time.
This AI-powered indexing happens automatically and repeats every time your course content is updated, so new or edited content becomes searchable without any extra work on your end.
ℹ️ This is also why enabling AI-powered search for the first time can take a little while: AI needs to index your entire course library before Context matches start appearing, and the more text content your catalog contains, the longer that initial indexing takes — typically a few hours.
Verbatim results vs. Context matches — and why we show both
When a learner opens search in Learnster U, they can type a question or a phrase in plain language. Search could return two types of results side by side:
Verbatim matches — traditional keyword matches on course and resource titles, just like before.
Context matches — excerpts that are matched by AI, these surface relevant excerpts from inside course content, even if the learner's words don't exactly match the text. Each result shows:
The course name the excerpt belongs to
A short snippet of the matching text, with the option to expand and read more
A link that jumps the learner directly to that part of the page — no need to browse through the whole course to find it
These two result types work differently, and each is better suited to a different kind of search:
Verbatim results look for an exact match between the learner's search words and course or resource titles. They're fast and work well even for very short searches — for example, searching just "GDPR" reliably surfaces a course titled "GDPR Policy." AI-based Context matches, on the other hand, need enough words to understand what the learner means, so it might not return relevant results for single-word or very short searches.
Context matches look for meaning rather than exact wording, searching inside course content (description, syllabus, page content) rather than just titles. This is what makes natural-language questions like "how do I handle a customer refund?" work, even if no course title contains those exact words.
ℹ️ Context matches are best when a learner is describing what they're looking for or asking a full question, rather than typing a single keyword.
Here's roughly what to expect depending on how a learner searches:
A learner searches... | Verbatim results | Context matches (AI-powered Search) |
A single word or short phrase (e.g., "GDPR") | Likely to appear, if it matches a title | May not give accurate matches, might be too short for AI to interpret meaning |
An exact course or resource name | Appears reliably | May also appear if the context is presented in course description, syllabus or page content |
A full question (e.g., "how do I handle a customer refund?") | Unlikely. Result appear if a keyword match is present | Most accurate — AI interprets the meaning and surfaces matching excerpts |
A topic described in different words than the course uses (e.g., "money back" instead of "refund") | Won't match unless those exact words appear in a title | Most accurate — AI interprets the meaning and surfaces matching excerpts |
In order to cover different search approaches, Learnster U shows: Verbatim results catch quick, exact lookups that Context matches could miss, while Context matches surface relevant content that a keyword search would never find. Together, they give learners a good chance of finding what they need, however they choose to phrase it.
Search results respect permissions
Learners only ever see search results from content they're allowed to access:
Courses they're enrolled in or assigned to → full content excerpts are shown.
Courses visible in their catalog but not yet enrolled in → only the course description and syllabus are shown as an excerpt in the "Context matches" search results. The learner is prompted to enroll to unlock the full content.
Courses outside a learner's access are never surfaced, regardless of query.
Enabling AI-powered search in your platform (for Super admins)
AI-powered search is available to Core-plan customers and is off by default.
Super Admins can enable it in following steps:
Go to Studio → Settings → General → Search in Learnster U
Turn on the AI-powered search toggle
ℹ️ Important information:
After enabling AI-powered Search setting, a delay of few hours is expected before Context matches start appearing while your content is indexed for the first time. The system needs to index your entire course library before Context matches start appearing, and the more text content your catalog contains, the longer that initial indexing takes, typically a few hours.
If you turn off AI-powered search, search in Learnster U reverts to the previous keyword-based behavior
Tips for content creators: making your content easier to find
A few content habits make a real difference in how well your courses surface in AI-powered search:
Write clear, descriptive course descriptions and syllabi. This matters more than it might seem: for courses that are visible in a learner's catalog but that they haven't enrolled in yet, only the course description and syllabus are searchable — not the full page content. A vague or empty description means that course effectively won't surface in search for those learners, even if the content inside it is exactly what they need.
Use clear, descriptive course titles. Verbatim results match on titles, so a title that reflects how learners would actually describe the topic — rather than an internal or abbreviated name — is more likely to surface in a quick keyword search.
Write page content in full, natural sentences where possible. Context matches work by understanding the meaning of your content, so pages written as complete thoughts tend to match learner questions more reliably than sparse bullet fragments alone.
Known limitations
AI-powered Search covers text-based course content only: course pages, descriptions, and syllabi. We're already looking into extending this to other content types, such as resources, video transcripts, and PDFs, so more of your content becomes searchable over time.
Very short or single-word searches are better served by Verbatim results; Context matches work best with fuller questions or phrases. Verbatim and Context matches are displayed in separate lists, but we are looking into merging the two lists for a better user experience.
User permissions are applied to content searchable in the Context matches. We are looking into making this more flexible so that you can choose more freely if a course should be available in the Context match search results regardless of permissions.
