title: WooCommerce REST API using custom attributes in search
body: <p>I've seen this question asked a couple times but nobody has any answers..</p>
  
  <p>I can't seem to get the REST call for /products working either? I can successfully make a call (over http) with params: seach, orderby, perpage and all the oauth_* params. I am trying to now query the same url with custom attribute for barcode. Documentation says add a param called attribute(barcode) in my case and then add attribute_term for the variable, but every call returns same data as the original blank parameter products call..</p>
  
  <p>Is anybody having any luck with custom attributes here? V1 api (not legacy).. Over http..</p>
