SharePoint 2010 Search Service DB. The database search_service_application_crawlstoredb is not accessible (Object Explorer)

Hi,

I am getting the below error while open the SharePoint Search Crawl database in SSMS.

"The database search_service_application_crawlstoredb is not accessible (Object Explorer)"

Last week i have detached some unwanted SharePoint Databases from the server.

Before detach i have taken the list of SharePoint Farm Level associated Database then removed which was unwanted.

Now I am getting the error like the above and while do Search in SharePoint portal. I am getting error like

"the search request was unable to connect to the search service"

Could anyone tell the exact reason.

Thanks &
Poomani Sankaran
