Error: Your search cannot be completed because this site is not assigned to an indexer. Contact your administrator for more information.
My Resolution:
- Open SharePoint Central Administrator
- Go to "Application Management" tab
- Click on "Content Databases"
- Click on the database name. Default name would be "WSS_Content".
- Select "Select Windows SharePoint Services search server" from the drop down.
You don't need to configure this manually if you installed Windows Sharepoint Services 3.0 in standalone mode.
