How do you find a missing cat?

My spayed female cat has been missing for two weeks. I have a cornfield on one side of me with coyotes in it and some woods that aren't too dangerous. I've put up and handed out missing posters but no one has called back. I haven't gone to every single house, though. I haven't seen her on the road, either. I just need madami ideas to find her. We have no paved roads. Tractors are busy this time of taon in fields my family doesn't own. I don't know what I'm supposed to do other than hand out missing papers.
