The goal is to create a view to list users on a page with url /search/[category]/[topic]/[location] where "category" "topic" and "location" are taxonomy fields in nodes that users can create.
I want to list all users that have a node were the "search" queries apply.
/search/all/all/all should list all users
/search/all/topic1/all should list all users that created at least one node with topic "topic1".
/search/category1/topic2/location3 should list all users that have created at least one node with taxonomy terms "category1", "topic2" and "location3".
Edit: I have machine names for my taxonomy terms and that is how I would like to use in the url.
