Members' posts

When i think some member has written a post i would like to read again but i don’t remember precisely in what topic it has been published, i click on " members " at the top of the page but this does not give me at all all the posts published only by this person. Only the number of replies, topics s/he has done

Would it be possible, typing a name, to get the list of his posts or at least the topics ?

The amount of badges he has got does not seem as important …

I wanted to show you the screen print with “no result” appearing after i chose a name, but there is no possibility to add a picture in this topic “help”.
Why ?
