json-server : how to do complex queries

Question

I have a set of users each with a team id.

I have a set of records which are 'owned' by a user.

e.g.

users: [
{ id: 1, teamId: 1234 },
...
],
records: [
{ id: 1, usersId: 1 },
....
]

Can I issue an API call to json-server that either

1. gets all records owned by users with a specific teamid?

   /records?users.teamId=1234

   According to the API guide I've found, this should work but doesn't. Adding _expand=users onto the query does seem to show the tables are linked.

2. alternatively gets all records if I provide a list of userids to filter on?

   /records?usersId=[1,2,3,4]

Is there any complete documentation on what you can do on the json-server API?
