I'm using a selfmade script to keep track of the packages that I have built and installed from the AUR. It's a bit similar to yaourt, but not as involved. One of the functions in the script is to check whether my installed AUR packages are up to date. This check basically consists of a loop which uses curl to make one search on the AUR search page per package. I believe all scripts that have similar functions do it like this as well (looping and searching one package per iteration, that is; I did only check yaourt, but how else could it be done?).

Now, to the FR; it would greatly speed up the scripts, and also reduce the load on the AUR web server (and likely the db server) if the search "engine" allowed for searching multiple packages at once, e.g. one could input "bfr dstat e-uae" in the search form to make it search for these three packages in one go. (To make it a bit better one could allow for combining search keywords with AND and OR and such.)

Furthermore, a way for making "exact" matching would be a good thing. That way, I could tell my script to query the AUR for the three packages which _exactly_ match "bfr OR dstat OR e-uae", thus getting out the exact information I needed for judging whether the packages installed on my system were up to date.
