Find not working as it should

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Add markers to map
2. Set property to each marker
3. Try to find a marker with X property value a setVisible on it.

What is the expected output? What do you see instead?

I have property "brands" set on each marker. I want to find brands with id of 
"8", I do: ["8"]

It only returns the ones that have "8" at the begining of the array. 
(["8","5"]). Also, can't find with multiple ids, like: ["8","10","9"]

rc1
