Parameters For A Match

I have used match before and discontined because I kept getting "matches" way out of my mile range that I entered.....even out of state! I wrote the reason in the "why I discontined" questionaire. Months later I decided to try again and see if there were any changes. I just started a couple of days ago and ALL my matches today (15) were in Portland OR! What is the reason for this? So it looks like we are getting a lot of matches? I am a single mom with two kids and I feel like I am wasting my money on a process that isn't working well. I also put in an age range and that doesn't seem to matter. Can you help me?
