Node.js and Mongoose regex query on multiple fields

Question

I would like to query multiple fields using the same regular expression for both. In this query, I would like to accept a single text input and check both the firstName and lastName fields for results. I can query a single field just fine using the regex function in the mongoose documentation, but the syntax for an 'or' clause is giving me trouble.

var re = new RegExp(req.params.search, 'i');

app.User.find().or([{ 'firstName': { $regex: re }}, { 'lastName': { $regex: re }}]).sort('title', 1).exec(function(err, users) {
    res.json(JSON.stringify(users));
});

(I'm running mongoose 2.7.1 on node.js 0.6.12)

Solution

The code above works fine for a query on multiple fields. Turns out I had some bad data.
