filter is not a function

[kagahd]

Classic findOne() works:

mongo-seometadata-01(mongos-3.4.15)[mongos] seo-metadata> db.oopmetadata.findOne()
{
  "_id": {
    "siteId": NumberLong("10"),
    "productId": NumberLong("3395201")
  },
  "index": false,
  "lastModified": ISODate("2018-09-14T12:22:12.070Z")
}

But filter() wont work:

mongo-seometadata-01(mongos-3.4.15)[mongos] seo-metadata> db.oopmetadata.filter()
2018-09-14T15:44:42.755+0200 E QUERY    [js] TypeError: db.oopmetadata.filter is not a function :
@(shell):1:1

My mongo shell is v4.0.0, perhaps that's the reason that something is incompatible with it.

Adding collection.filter() as an alias for collection.find() doesn't seem constructive. I'm not sure if this existed previously, but I've removed the mention from the README.
