REST API query to return last few computers for a user

Hi, I only just started using the REST API and relevance code. Its a bit overwhelming :slight_smile: I am trying to get my head around the relevance code for a web reports query. I try to learn through examples so I am trying to create a string for /api/query?relevance= to return the following, given a username return the last few computers that user has logged into. Would someone know how to do that or am I going about this the wrong way? Any help appreciated
