Unable to query on two indexed fields with 1 being date [Datastore]

[DaveyEdwards]

Environment details

• OS: Windows 10
• Node.js version: 6.11.2
• npm version: 3.10.10
• google-cloud/datastore: "^1.1.0",

I am unable to pass in multiple query filters if one of them is checking for a date. It gives the error Your Datastore does not have the composite index (developer-supplied) required for this query. It also produces this result if I try to sort based on the date.

In the indexes tab inside Google Cloud console there is nothing. Any information I try to find about this it talks about having your index composites inside index.yaml. With google-cloud-node I do not have this yaml file, and don't think I need it? If I do where would I need to connect it.

Query filter by date + _id (both indexed) not working

Querying date alone works

Querying matched _id works

Multiple query filters do work

Check out the Index docs! They will do a better job than I can explaining what a file looks like, when/why you need it, and how to use the gcloud sdk to create them.
