Some problems about the rest API's introduction

[StevenWash]

Excuse me , I have a problem in how to use the '_query' in the rest API . For example,I find it is little difficult to understand the introduction of _query in Credential's API . I have try to use params like this:

I have deleted some other unused params.The result is correct.
But ,if I want to query userId="AQ" ,so what params should I input？
I have tried like this:

But the result was the same as above result(without the param userId="AQ").
So can you give me a suggestion?
And I also hope that the introduction of each API should be more detail.
Thank you so much!

Hi @StevenWash ,

As said in #714 we don't currently support filtering with query.
Filtering parameters available are those exposed by the GET method

So maybe we should create a new issue for tracking this.

This implementation will be tracked in #803. Please use that issue to continue the discussion.
