It appears that jiraJqlSearch uses "jql", "startAt" and "maxResults" parameters for calling Jira REST API with api/2/search endpoint. 

Jira admin at Teradata where I work wants api/2/search call to be made with "fields" parameter to avoid negatively impacting Jira performance when we update Jira to version 7.13.5. I noticed that your code does not use fields parameter.

Is it feasible to add fields parameter so I can continue to use jiraJqlSearch in my code for work?
