Custom fields in XML export url

Question

Hello,

I want to customize the columns (fields) in a XML export url.

It is possible adding "&field=fieldname" at the end of the URL, like this example where I get the summary and Priority of all the issues created by a user:

....jira/sr/jira.issueviews:searchrequest-xml/33376061/SearchRequest.xml?jqlQuery="creator%20in%20(username)"&tempMax=5000&field=summary&field=priority

In this example I have no problem, but I don't know how to get fields whose names have spaces, for example a field like "&field=date end progress schedule" it does not work  ( I tried &field=date%20end%20progress%20schedule too)

Thank you

Hello, I found the way. 
In the field part of the url, spaces must be codefied as "+" not as "%20"

An other problem for me was that the field "date end progress schedule" is a customize feild, so in the url must be set as customfield_<number>
