In SharePoint 2019, developers can leverage Hybrid Search to connect on-premises SharePoint environments with SharePoint Online. This feature is particularly beneficial for government entities needing to keep sensitive data on-premises while utilizing cloud search capabilities.
Steps to Enable Hybrid Search in SharePoint 2019
1. Configure Server-to-Server Authentication with Azure AD
- Register your SharePoint farm in Azure AD as an enterprise application.
- Generate a client ID and client secret for authentication.
- Use PowerShell to establish trust:
New-SPTrustedSecurityTokenIssuer -Name "AzureAD" -Description "Azure AD for Hybrid Search" -IsTrustBroker -MetadataEndpoint "https://login.microsoftonline.com/<tenant-id>/federationmetadata/2007-06/federationmetadata.xml"
2. Set Up Cloud Search Service Application
- Navigate to SharePoint Central Administration > Manage Service Applications.
- Create a new Cloud Search Service Application.
- Configure the crawl component to index on-premises content.
3. Configure Hybrid Search Topology
- Use PowerShell to map the search topology:
$ssa = Get-SPEnterpriseSearchServiceApplication New-SPEnterpriseSearchHybridCloudTopology -SearchServiceApplication $ssa -CloudSsaId "<cloud-ssa-id>"
4. Verify Hybrid Search Connectivity
- Run a test crawl and check the Search Results page in SharePoint Online.
You Should Know:
- Azure AD Sync Requirements: Ensure Azure AD Connect is properly syncing user identities.
- Firewall Rules: Allow outbound traffic to `.sharepoint.com` and
.microsoftonline.com. - Troubleshooting Commands:
Get-SPEnterpriseSearchStatus -SearchApplication $ssa
Repair-SPEnterpriseSearchHybridCloudTopology -SearchServiceApplication $ssa
What Undercode Say:
Hybrid Search in SharePoint 2019 bridges security and efficiency, allowing organizations to maintain data sovereignty while leveraging cloud-powered search. Key commands like `New-SPTrustedSecurityTokenIssuer` and `New-SPEnterpriseSearchHybridCloudTopology` are critical for deployment. For Linux admins, similar hybrid models exist in Elasticsearch and Apache Solr, where federated search across on-prem and cloud nodes is possible using REST APIs.
Expected Output:
- Successful hybrid search results in SharePoint Online displaying on-premises content.
- Logs in Central Administration confirming crawl completion.
- Azure AD audit logs showing successful token exchanges.
