DBCC CHECKDB Corruption in Search_Service_Application_CrawlStoreDB

Question

After some recent server issues, the SharePoint full backup keep getting an error when checking for database integrity. The following error message is thrown in SQL logs:

DBCC CHECKDB (Search_Service_Application_CrawlStoreDB_SomeGuid) WITH no_infomsg executed by DOMAIN\SomeUser found 216 errors and repaired 0 errors. Elapsed time: 0 hours 0 minutes 43 seconds. Internal database snapshot has split point LSN = SomeNumbers and first LSN = SomeNumbers.

Our only solution up to now is to make a restore of the database (last one yesterday 12:00pm), but before doing so, what are the impact of losing 24h of data in this database? Is it related only to search results? Will a new Crawl refill the missing data?

Answer 1

I am not seeing any major impact but you have to run a full crawl after restoring the database.

I think you can create new crawl database and detach the old one then run a full crawl.

if you have too many times then may be a full crawl will take time.

The Crawl Store database stores the state of each crawled item and provides the crawl queue for items currently being crawled.
