Searching stories on mugglenet fanfiction is a bit of a pain. You can only set it for raitings, warnings, alphabeticaly or most recent, or completed, work in progress, and all stories. Personally I hate looking at hundreds of one shots before even getting to a story with more then 2000 words.
I think that a word count should be added to the search. ranging from 0-1000, 1001-5000, and so on. I think that it would help the search for a good story much shorter.
