[Users] REST API query syntax

Hi, all I learned some query language from "REST API User Guid" to get a reduced result list, for example: /api/storagedomains?search=name%3D*iso* it works. but the following querys do not work /api/storagedomains?search=type%3Diso /api/storagedomains?search=id%3D3f00108a-5c0e-4723-aa88-0013773bf122 /api/vms?search=display.type%3Dvnc I don't know what is the difference between them, and which property can be act as the part of query ? thanks!
