Quoted from existing question.

Since the original question has been closed and couldn't be replied, try to post this new question.

I'm trying to retrieve the assignee email address and project key from a JIRA search query via REST call - I can't seem to limit the returned fields to just theses 2 fields.

Example:

https://jira.atlassian.com/rest/api/2/search?startAt=2&jql=project%3DANERDS+and+updated+%3E+2013-04-29&fields=project,assignee&maxResults=2

will return

{
expand: "schema,names",
startAt: 2,
maxResults: 2,
total: 38,
issues:  [
 {
expand: "editmeta,renderedFields,transitions,changelog,operations",
id: "280877",
self: "https://jira.atlassian.com/rest/api/2/issue/280877",
key: "ANERDS-473",
fields:  {
project:  {
self: "https://jira.atlassian.com/rest/api/2/project/ANERDS",
id: "12510",

name: "Angry Nerds",
avatarUrls:  {

48x48: "https://jira.atlassian.com/secure/projectavatar?pid=12510&avatarId=12492"
}
},
assignee:  {

Doing fields=project.key,assignee.emailAddress does not work either...

Alek has replied that “There is no way to get only project key and assignee email address in JIRA REST API (for issue search results).”

6 years has passed， Is there a chance this feature to be included into API?

@饶青There is no development in limiting amount of information we get per issue field as of Jira 8.
