Search on Identifiers Field

Hi:

I am trying to conduct a search on the identifiers field and I am having trouble getting results on any id type except for isbn, can someone help me figure out how to get a search for a goodreads and amazon identifier? This is what I am inputting but I am getting no results:

identifiers:goodreads
identifiers:amazon

Here is what an example file has in the ids field but it only comes up as a successful search using asin.

isbn:9781893896840, amazon:1893896846, ff:a/keri-arthur/chasing-shadows, goodreads:189359, google:4tA_cAAACAAJ
