Full Text search in mongodb 2.6 with meteor .toArray error

I am making this work with meteor exporting mongodb to a 2.6.6 separate database and send the results to a array to get published. It is returning this error. How can it be fixed?

I20141224-16:55:52.410(-5)?  Exception while invoking method 'ftsearch' TypeError: Object [object Object] has no method 'toArray'

Meteor.methods({
    ftSearch: function(req) {
        Posts.find({
            "$text": {
                "$search": req
            }
        }, {
            posttext: 1,
            submitted: 1,
            _id: 1,
            Posts: {

 Meteor.ensureIndex("posts", {

var postId = Posts.insert(post);

return postId;
