Searching pairings on mugglenet fanfiction is a bit of a pain. You can only set it for pairings such as Harry/Ginny and Ron/Hermione. If someone wants a fic containing a pairing such as Sirius/Ginny or Hermione/Victor in the Other Pairings category. Personally I hate looking at hundreds of fics before even getting to a story which is remotely what you are looking for.
