Finding usages/references of Java elements

I'm not implementing a custom language, I just need to be able to see references for Java elements. Essentially, I'm grabbing the same data that appears in `Find Usages`.

When I use:

ReferencesSearch.search(method).findAll();

I get a list of references with the correct number of references, but they all return the same method that I put in, even when I resolve those references.

For example, if I had some code that looked like this:

void myMethod() {
    // Do stuff
}

void callMyMethod() {
    myMethod();
}

And I found references for `myMethod`, I would get `myMethod` in the list of references.

How do I get `callMyMethod` in the list of references? If I did a `Find Usages` search in the IDE, it would give me `callMyMethod`. It would also be great to get the character offset in the code itself for the method call. (so if my example were the entire file, it would give me a character range of 68 to 76), but maybe once I'm pointed in the right direction I can figure that out on my own.

I've tried getting inspiration the actual `Find Usages` code instead, but it seems very tied to the UI and IDE. I need something that has no attachment to the UI, but if there is not an easy way to do it, I will continue to go down that route.
