title: REST: Mapping 404 HTTP Status codes
body: <p>Our team is developing RESTFul applications...we are debating the "BEST PRACTICE" approach.</p>
  
  <p>Should 404 status code response be returned for a filter-like query? Say my GET URL is </p>
  
  <p>.../1/service/startsWith/a.json</p>
  
  <p>and it returns all values that start with A in my database...but if no "a" values are found should i just return status code 200 with an empty json string? or status code 404.</p>
  
  <p>Thanks!</p>
