Searching in Twitter - There has to be a better way

I know on Twitters search you put in a search word to find other people who are supposedly interested in the same niche but what I'm getting is tons of bullshit.
For example, let's say I want to promote adult dating. If I put "adult" in the search or "adult dating" or whatever, all I'm getting is results of people who have used those keywords in the tweets. I could get granny in Florida who has a tweet about her adult grandkids visiting.

How do we search for people that are really interested in our particular niche?

I'm not sure if this is exactly what you're looking for, but it's a quick read on some search tips that you can build on to identify your targets.

try twellow, it's a directory of people in twitter, but not sure if there's an adult category there.

the only problem is people add themselves to the wefollow list. the good news is they tag themselves they way they want.

Seriously
