Thanks for confirming that! Do you think we should add a `findOne` method to the adapter that wraps the `find` method like:
````javascript
find: function(collectionName, params, cb, unique) {
    ...
    query(q, params.where, cb, !!unique);
},

findOne: (collectionName, params, cb) {
    return this.find(collectionName, params, cb, true);
}
````
