I am looking for a method which partial search for integers in mongoose.

I have a collection of objects that have a property called `incidentId` (Integer). I am passing the `incidentId` to the function (for exeample: 1) and I am expecting the results to be all the objects that have `incidentId` starting with 1 (for example: 1, 10, 11, 12 ... 100).

I tried using regular expression (before realizing I can't use it with numbers) like this:
`foundIncidents = await this.db.find({documentType: 'INCIDENT', 'incident.incidentId':{ $regex: incidentId, $options: 'i' }});`

I cannot modify the DB schema in order to change the `incidentId` to String.

If you need any more information let me know.

Thank you
