I just made the proposal Networking (which was closed as a duplicate). However, before i created it i did a search for network, networks, and networking, and didn't find anything. However, a previously closed proposal named networks exists, but it was buried under about 20 other results, so i didn't see it.
It just seems to me that the search/result is a bit counter-intuitive to me. Maybe i just don't understand what the search is for.
