Return array from a mysql query in nodejs

I'm facing a huge problem here, and I don't know how to solve it:

I have a simple route (which works) in nodejs made with express:

    public static create(router: Router, basePath: string) {
    console.log("[SearchRoute::create] Creating routes for /search.");
    // call the function for retrieving the address book results
    router.get(basePath + "/search/:searchString",
    function (req, res, next) {
    console.log(searchUser(req.params.searchString));
    });
    }

And i have the searchUser function with a simple query:

    function searchUser(searchString) {

    console.log("searchUser Function executed.");
    return myMYSQL.connection.query('SELECT XXX FROM XXX WHERE ?',[searchString],
    function (error, results) {
    if (error) throw error;
    return (results);
    });

The problem that I'm facing is:

In searchUser, the result of the query it's giving me 2 objects.

But in the route (the first function), it's only printing me one result in the values index of the result.

I think the error it's in the return of the searchUser function, I'm somehow returning it wrong and missing something.

Thank you so much to all for your help!
