We might encounter Error while creating site "Unhandeled exeption was generated during the execution of the current web request"

After enabling stack trace users getting 'Boolean Microsoft.Office.Server.Search.Query.Scope

method not found :'Boolean Microsoft.Office.Server.Serach.Query.Scope when they try to browse the site.

ERROR MESSAGE:

====================

Unhandled exception was generated during the execution of the current web request"

After enabling stack trace we see

'Boolean Microsoft.Office.Server.Search.Query.Scope

method not found :'Boolean Microsoft.Office.Server.Search.Query.Scope

The issue occurs normally if we don't follow the order of installing the patches on MOSS

RESOLUTION/WORKAROUND:

====================

Installing latest patch on all the server and then running the configuration wizard should help us to resolve the issue.
