This is my first go at my SearchResource. So far, it is able to list out the users, , groups and review request. Through /api/search/?q=<keywords>, it is able to filter through username, first name, last name of a user, name and display name of a group and the ID of a review request. I am currently missing the ability to search the summary of a review request. 

Please take a look if I'm on the right track or if there is anything for improvement. Thanks!
