How to run a query on a CouchDB collection

Question

I'm working in NodeJS and I have a working CouchDB connection.

I can get a reference to a collection like so:

var myCluster = await couchbase.connect(serverHttp, authentication);
const myBucket = myCluster.bucket("myBucketName", { timeout: 10000 });
const myCollection = myBucket.defaultCollection();

This all works as I can make a call like so:

const res = await myCollection.get("testKey");

and indeed I see that res contains the one document from the database which has its id as "testKey".

Question: How can I run queries on myCollection?

For instance, the most trivial example, how could I retrieve from myCollection all of the documents in it?

Or, if this is not possible, how could I achieve the same by using myCluster?

This is not working for me:

var result = myCluster.query("SELECT myBucketName.* FROM myBucketName");

Thanks for any help.

ADDENDUM: ok, I have found this way that works for me:

var result = await myCluster.query("SELECT META().id, * FROM myBucketName");

I still have a lot to learn!
