"smart search"

Hello all,

I created a blog which lists restaurants and bars all around the world. I’m having difficulties to make people search these adresses. If I go on the blog’s search engine and that I type “rome”, he will give me results with promenade, etc.

Is there a plugin out there where I could set up smart searches? for example enter values which will be the cities for example “los angeles” with all the posts about los angeles?

Please help, i’m driving nuts here 🙂
