$regex support in Stitch - using mongodb-stitch-react-native-sdk

[jug smith]

Hi guys,

Is there a different way of using $regex with Stitch while using the react-native version of the SDK?  Or is there a different way I should use  $regex?

I'm able to use $regex from the Mongo Shell.. but I don't get the correct results back when I use it from my react-native app.
I get some results back but they're not filtered by my $regex query below. 

---

import { BSON } from 'mongodb-stitch-react-native-sdk';
const numposts = 10;
const queryString = 'versatile';
const regexp = new BSON.BSONRegExp(queryString, 'i');
const query = 
{

$or: [

{ "name" : { $regex: regexp, $options: "i" }},

{ "title" : { $regex: regexp, $options: "i" }},

{ "brand" : { $regex: regexp, $options: "i" }},

{ "details": { $regex: regexp, $options: "i" }}, // this is an array, everything above is an individual string field

]

};
const coll = db.collection( itemsCollection ); 
const options = {"sort": {"_id": -1}, "limit": numposts};
const prom = coll.find(query, options).toArray().then( items => {

console.log(items);

});

Thanks,

Raj

Any help or pointers would be appreciated. Thanks
