I've disabled nepomuk as my mail resides on a local IMAP server and I connect online to that server. Since I connect online, I assume only some part of mails are downloaded so there's no way nepomuk could index everything. Anyway, mail server (dovecot) already has the indexing running so server side searches are very fast.

In Kmail2, I'm trying to do a search but I'm presented with a dialog which says "You have disabled full text indexing of emails. Searching is not possible without that. You can enable it in "System Settings"."

This is true, but I don't need Kmail2's full texts indexing, I just want it to make an IMAP server side search.

This is also needed when your server is very remote and you work in online mode, without downloading all mails.

Reproducible: Always

Steps to Reproduce:
1) disable nepomuk and full text indexing on the account and folder if necessary
2) try to search for something using "Find" dialog (S)
3) see that you're presented with the dialog box


Expected Results:  
Server Side search shall work.

If I'm missing something and if there's other method to do server side search, please let me know.
