How do I add sites associated to a different hub to a hub's search scope in SharePoint Online?

[Thomas_Randall]

So, I have the following problem with searching documents in SharePoint Online:

Setup:

• Tenant

  • Hub A - Agency A Intranet

    • Hub B - Department J Intranet

      • Site M - Division 1 Site

      • Site N - Division 2 Site

    • Hub F - Department K Intranet

  • Hub C - Enterprise Project Management Office (EPMO)

    • Site X - Agency Q Project

    • Site Y - Division 1 Project

    • Site Z - Division 2 Project

  • Hub D - Agency P Intranet

  • Hub E - Agency Q Intranet

The EPMO owns all projects for the organization. My business users project-related documents to come up in their Department's Hub search results.

Requirements:

• On Hubs A & B:

  • Search results should include Sites M, N, Y & Z.

  • but NOT site X or anything in Hubs D or E.

• On Hub F:
  • Search results should NOT include Sites M, N, Y & Z.
• On Hub C:
  • Search results should include Sites Y & Z.
  • Search results should NOT include Sites M & N.
• On Hubs D, E, & F:
  • Search results should NOT include Sites M, N, Y & Z,

• On Site M:

  • Search results should include content on Site Y.

• On Site N:

  • Search results should include content on Site Z.

• On Site Y:
  • Search results should NOT include content from Site M.
• On Site Z:
  • Search results should NOT include content from Site N.

I have found instructions to increase search up in a hierarchy from Site -> Hub -> Tenant, but not adding results from only certain other sites.

Is this possible? If so, can anyone point me to the documentation to set this up?

Thank you!

Hello @Thomas_Randall 

i think it's not possible, the Microsoft Search is scoped only to the Hub, but you can't add elements from other. But you can user the PnP Modern Search WebParts to show more elemnts from different sites.
