Search is everywhere in Microsoft 365. You can search from SharePoint, Teams, Delve, Yammer etc.
But! From SharePoint you cannot search for Teams chats (*1).
From Teams you cannot search for regular (no-group) sites.
Sites descriptions are totally out of search (including Yammer groups, Teams and regular sites).
So, what are the scopes of each search entry point in Office 365 and is there an entry point you can search for everything?
| Search scopes | SharePoint Search center | SharePoint home Office portal Office desktop app Delve | Teams | Bing |
| SharePoint content | Yes | Yes | Yes | |
| Teams content | Yes | Yes | Yes | Yes |
| Teams chats | (*1) | Yes | Yes | |
| Yammer content | Yes | Yes | Yes | |
| Yammer chat | (*1) | Yes | ||
| User profiles | Yes | Yes | ||
Detailed:
| Scope | Out of Scope | |
| SharePoint Search Center | – all sites content (Teams, Yammer, regular), – user profiles – OneDrive | Teams chat Yammer chat |
| SharePoint Landing Page | same as SharePoint Search center but Teams chats and Yammer Conversations are coming | same as SharePoint Search Center |
| Office.com | same as SharePoint (Teams chats and Yammer Conversations are coming after SharePoint) | same as SharePoint |
| Delve | ||
| Teams | Teams content Teams chat | OneDrive Yammer User Profiles regular SharePoint sites |
| Bing | Everything* | * except people profiles content (e.g. about me) |
Seems like the only tool you can search for EVERYTHING with is Microsoft Bing:
After Microsoft add Teams chats and Yammer conversations to SharePoint landing page search scope (then to Office home page) – it’ll be the best place to search from for everything.
