How Does Microsoft Search Compare to Competitors?

vs Glean

Microsoft is focused on Microsoft 365/Azure Customers through integration into their respective ecosystems. Microsoft has better compliance reporting however it limits its ability to integrate data sources outside of the Microsoft Ecosystem.

If you have a Multi-SaaS Environment choose Glean; if you are an Enterprise that is heavily invested in Microsoft 365 Choose Microsoft.

vs GoSearch

Per User Pricing is less complicated than Microsoft's Compute Tiered pricing structure (GoSearch supports over 100 Data Connectors).

GoSearch for Quick Unified Workplace Search; Microsoft for Governed Enterprise Deployments.

vs Algolia

Developer Speed/Custom UX/E-Commerce (Algolia) and Enterprise Knowledge Management within Microsoft 365 (Microsoft). Algolia is better suited for Custom User Experiences.

Public Facing Search (Algolia); Internal Enterprise Knowledge Bases (Microsoft).

vs Coveo

Both are Enterprise Focused and provide Relevance Tuning. However Microsoft utilizes Microsoft Graph to leverage additional Contextual information; Coveo focuses on Content Personalization across multiple Platforms.

Diverse Content Sources (Coveo); Microsoft 365 Users (Microsoft).

What do expert reviews and research say about Microsoft Search?

Key Findings

Microsoft Search offers one unified AI-Powered search experience over Microsoft 365 and includes strong Graph API integration and Graph Connectors for searching external data. Microsoft Search is native to every commercial M365 plan and allows admins to customize their own search experience. While Microsoft Search may eventually be replaced by Copilot Search (potentially around 2025), the core search functionality will remain available.

Data Quality

Good - official Microsoft documentation comprehensive. Support/pricing details require M365 licensing context. Product evolution toward Copilot impacts roadmap assessment.

Risk Factors

!
Microsoft is shifting its focus towards investing in Copilot Search, which may result in features from Microsoft Search being retired.
!
Currently limited to Microsoft ecosystem (has weaker multi-vendor support).
!
Quality of search results depend on how complete the Microsoft Graph index is.
