The Semantic Index is a new feature (April 2024) in Microsoft 365 that uses Microsoft Graph to enhance search and Copilot experiences by creating indices for personalized and organizational data.
An example: query for “Apple market growth”
- Traditional search: searches for apple, market and growth.
- Semantic index: interprets the query in its context and results in growth of Apple Inc., the technology company.
It provides contextually relevant search results by analyzing vectors representing data features, supporting a richer understanding beyond direct keyword matches. Key features include enhanced security that respects organizational boundaries, integration with Microsoft Copilot for context-aware assistance, and improved search capabilities in various Microsoft 365 applications.
