I’m working on a sharepoint project.
After I adding the search web part. The search function behaves weird.
I have crawled the content source and configured the permission.
The following search bar, no matter what I search, I got nothing

But the advanced search web part can work properly.

The thing is, in the result page of the advanced search web part, if I choose to see the result of my sharepoint website instead of "Any Site", I got nothing. I am sure that the result of "Any Site" is from my sharepoint site.

Any ideas will be appreciated.

You need to check your search log to make sure content is being crawled correctly. It looks like you do not have any results for your a particular site. modify your search webpart to show the scopes drop down an experiment to find out which scopes are not responding correctly and debug from there.
You need to ask this question on serverfault.com or sharepoint.stackexchange.com as this site trys to deal with programming specific errors only.
