Event ID 6482: Search not provisioned: There is no project Portal_Content mounted under gatherer application guid

Question

My search service shows this message 
My search service shows this message:  'The search application 'Search Service Name' on server SERVERNAME is not provisioned. Confirm that the Microsoft SharePoint Foundation Timer service and Central Administration service are running on the server'.
 No changes can be made.  I am able to run search queries.
Every minute the Application Server Administration job tries and fails to provision the service and logs the event id 6482: Search not provisioned:  There is no project Portal_Content mounted under gatherer application <guid>
I've found a few posts online that have solved this by clearing the sharepoint cache, which I've done a number of times without success.  A few others re-created search which isn't a real good solution for me since we have a lot of customizations that
would have to be redone.
Restoring from Central Admin backups is a possibility, but without knowing exactly what the problem is, it seems that this approach may cause further problems.
Thoughts anyone?  Here's the full event log message

Hi,
For your issue, try to do the following:
Go to Services, and then reset SharePoint server search  accounts (stop/start).
Reset the crawl index (clears the index).
Stop and then start the SharePoint Server Search  - Central Administration: stop and then restart the service.
Reset default content access account.
Besides,Here are similar issue post, you can use as a reference:
