I was having the same problem and unfortunately @josedlujan's answer does not solve the problem.
Alternatively, you my try the Ctrl+Shift+F to certainly find what you want, also double clicking Shift will open a quick dialog to find certain keyword in the whole project.

In my case I was not finding anything since I had "File name Filter" checked and I was just looking in build.gradle.
There are two options to resolve the problem:
1. Uncheck option "File name Filter" or,
2. Just filter to *.java or whatever type of file you want
