Guidelines and recommendatoins for the use of the AI-enhanced content search

Multiple Search Bars and Entry Points to Content

  • The AI-enhanced content search and the existing catalog search will continue to run in parallel until further notice. Please rest assured: we will not replace any current functionality without clear and timely communication.

    Left: catalogue search Right: new platform search

  • The two search functions are based on different technologies, approaches, and scopes—which is why their results may differ. imc plans to gradually expand the AI-enhanced search index to cover platform-wide content, including items that are directly assigned to users but not linked to any catalog or channel.

  • Currently, the AI-enhanced search covers all learning content from catalogs and channels which are accessible to the user searching. This makes it a strong candidate for becoming the primary access point to content. You may want to review whether some of the additional search bars—such as those in dashboard panels—can be hidden if they duplicate this functionality. Simplifying the interface can help reduce user confusion.

  • If your systems provides users with several search bars, you might want to consider to use titles or placeholder texts (within the search bars) to give the users a hint at what they search through in that particular case.

  • For your information: The navigation search, mainly used by admins and managers to find pages in the system, can still be accessed via the top navigation but now via this icon:

Data protection notice

  • Search queries are processed in such a way that they cannot be traced back to individual persons, but are associated solely with the technical system from which they originated. No personal data is collected, stored, or linked to specific users during the processing of search queries.

  • Search terms used in queries are stored exclusively for anonymized reporting purposes. In the near future imc will provide customers with a report designed to help customers understand general search behavior, such as commonly used terms and how many results were displayed. The report will not contain any data that would allow identification of individual users or their specific queries.

  • We recommend advising users not to enter sensitive or personal information into search queries, as these terms may appear in anonymized reports that could be accessible to administrators or others within your organization, depending on how data is shared.

Decide on the best search type for your organisation

  • As described in the functional reference the content search supports two search types or modes:

    • Lexical Search
      This mode directly matches the words from the user's query with titles, descriptions, and keywords of learning content. It’s a purely text-based lookup—no artificial intelligence involved.

    • Semantic Search
      In this mode, both the indexed learning content and the user’s query are converted into vectors using AI technologies. This allows the system to detect semantic similarities and retrieve related concepts and themes even if they are phrased differently from the query.

  • If your organisation does not want to allow any further AI services to be deployed to your system you can stay with lexical search. If the choice is on you, the following table can help make a decision.

Lexical search

Semantic Search

Ranking of results

Content with the exact words of the user query in the title will rank highest.
(Next: it’s in the description, then: keywords)

Advantage:
This is especially helpful, if the user looks for content he/she already knows.

This is the better option if users often search for numbers, codes and other numerical information, because this requires an exact match not a similar.

Challenge:

The user has to use the same wording as in the titles, keywording and description.

Content considered most relevant for the user query is ranked highest. Title and description are considered.

Advantage:
The user does not need to phrase his query exactly like the words used in the learning content. Synonyms and related topics are also found. A query about “problem with login” could also find “forgot password”. The search will understand the difference between a black box (container of dark color) and a black box (flight recorder) from the context.

Challenge:
The user might not see why the result is relevant, because the title might not show it. The algorithm is not reveiled to the user to give that explanation.

Pre-requisites

Usually none -
traditional searches work like this. Most users are used to it.

Users have to mind their spelling and keep the search queries rather short.

Data quality:
The semantic search relies on data and it needs context to interpret the meaning correctly. Your courses, learning paths and media should have meaningful titles and descriptions that give background information for the title.

User search behavior:

The more context a user provides with the query the better the results.

Example:

  • User query “french” delivers results about french fries, french kissing and all french language courses.

  • User query “I want to start learning french next month.” will provide only the beginner language courses starting next month.
