AI-Powered Search in SharePoint: Finding the Right File in Seconds
SharePoint will have subject matter experts in the form of AI-driven agents going forward.
When we ask people, “what is that one thing, if, is better, you’d use SharePoint more?”
Of what is mentioned, improved search methods are one of the most mentioned ones. Users imagine different ways of running the searches and that, if possible, could make their lives easier. Microsoft did hear it out, and advanced search got modified and is now far more advanced.
Key Improvements of Advanced Search in SharePoint Over Time
Some of the key advanced search improvements in SharePoint were done in 2023, 2024, and 2025.
1. 2023
Modern Search Experience Transformation
MS Search was introduced, where AI and MS Graph were used together for personalizing search results.
2. 2024
Highly Intuitive Search Process
Recognizing synonyms and similar concepts and identifying and aligning with user intent to improve the quality of searches began to make way.
3. 2025
PnP Modern Search Open-Source Introduced
Customizable web parts can help you opt for advanced filtering and use dynamic search experiences.
Search Options from Microsoft
SharePoint search: Originally built for the on-premises SharePoint, it is known for its tight integration with document-level user permissions for improving and making access control stricter.
Microsoft Search: SharePoint currently uses machine learning. It has a limited set of customization options and lacks document-level security settings.
Azure AI Search: It comes with sophisticated AI search capabilities. It would need suitable API implementations. Security trimming could need some work and does not add native document level security settings.
All of these take you one step closer to finding the right file in a short amount of time.
Advanced Search in SharePoint
Advanced search in SharePoint makes searching more efficient for specific content. Features like metadata filtering, Boolean operator use, and search refiner options can narrow down the search requirements, thereby improving advanced search capabilities significantly. Reducing the overall search time spent by users is what is possible with it.
