I mean this method I have tried it before, it did not work.

Option 1 is not available, I have already tried it.

Is it a bug? Why can anonymous access /crx/explorer/ui/search.jsp？

I just want to limit anonymous to access /crx/explorer/ui/search.jsp,  I don't want to stop WebDAV.

I tried to add +/crx/explorer/ui/search.jsp in Apache Sling Authentication Service, but it didn't work. How can I restrict anonymous access /crx/explorer/ui/search.jsp?

I tried these codes. But it occured error 'Caused by: javax.security.auth.login.FailedLoginException: Impersonation not allowed.' I cannot use workflow-process-service to impersonate other accounts. How can I solve this problem?

This is not Chinese character.

I know. I just use the admin credential to check it. But the inbox loads slowly even few items.

Even there are few items in inbox, it still needs a lot of time to load the page, spending about 10sec even more loading the page. How can I solve this problem? Are there any good ideas?
