Here's how:
1) Go to marketplace and select Energy Fields from the drop down
2) It'll take you about 60 pages of EFs (which I actually did look through by hand before I figured out this trick. Lol)
3) Up in the URL, at the very end, it should say "item plus = -1"
4) Change this to "item plus = 0"
5) Now there are only 4 pages, and as those EFs do not have a + value, any that are in the market will show up here
You're welcome
(if it doesn't initially have the item plus in the URL, just go to the next page, and it'll show up, just remember that this will take you to the second page of the 4 pages...)
