Does someone knows the syntax for searching articles only posted by a certain user, like i have now for instance :

binsearch.info/index.php?q=kid+cowboy&m=&max=500&adv_g=alt.binaries.comics&adv_age=1100&adv_sort=date&minsize=&maxsize=&font=&postdate="

That searches for kid cowboy posted in alt binaries comics with some more data, but now i want to list only the kid cowboy that is posted by for instance boutje.

Is that possbile at all ?

Thanks in advance.

The "author" field in the search service bar, the syntax is the same as for the subject, the subject field can be left empty.
