Hi there,
There might be many reasons for this behavior in Servers . You can try rebuilding the Search Index.
Open Control Panel > Indexing Options. In the Advanced Options, Click on Restore Defaults and also Rebuild Index. Click OK.
Type ‘services.msc’ in the run . Scroll down to the ‘Windows Search Service’, and ensure that it is set on Automatic and Running. Restart this Service. You will also have to ensure that RPC (Remote Procedure Call) is running and set on automatic.
