You can simply use

editor.session.getLength()

In short:

var found = editor.$search.find(editor.getSession());

Iterate over all lines and check indexOf

function findFooLineNumbers(editor, foo) {
    var lines = editor.session.doc.getAllLines()
    var fooLineNumbers = []
    for (var i = 0, l = lines.length; i < l; i++) {
        if (lines[i].indexOf(foo) != -1)
           fooLineNumbers.push(i)
    }
    return fooLineNumbers
}

You left too little information and you can not expect a great help

If you want to return more information at the same time u need Array

var number = new Number(5) // Single number. he will return just 5

You can try somthing like this to see how to return array

function test() {
    var IDs = new Array();
        IDs['s'] = "1 342 364,586";
        IDs['g'] = "123 324 646 876";

        for (var i = 0; i <= IDs.lenght; i ++ ) {
             // do somthing  
        }
    return IDs;
}

To check if return is realy nubmer use Number.NaN
