How to search for posts directly belonging to a user, instead of any post edited by that user?

I want to search for posts directly authored by a user, not merely being edited by a user.

Like (for example: stackoverflow.com/search) which shows, a lot of question, being edited by DaleK ?

Note the following: I do not mind seeing post from Dale, in general, but I did not like to see all the edits he does make.
