Search group/whitelist + wishlist?

Hi guys,
so far, I'm using two main paths in order to enter the giveaways I want:
https://www.steamgifts.com/giveaways/search?type=wishlist&copy_min=2 (which searches in my wishlist for giveaways with 2 or more copies)
https://www.steamgifts.com/giveaways/search?type=wishlist&level_min=6 (which searches in my wishlist for giveaways from level 6 onwards, or level 5 if I put 5 and so on)
Of course, I also keep the two "non wishlist" ones that make me find new games and giveaways that fall in the previous categories:
https://www.steamgifts.com/giveaways/search?copy_min=2 and https://www.steamgifts.com/giveaways/search?level_min=6

Though, it seems - I have tried everything I could think about and have read the thread with the new search options and so on - that it's not possible to make a research similar to the four above: searching for games BOTH in my wishlist AND whitelisted or group only

If you combine these two:

• https://www.steamgifts.com/giveaways/search?type=wishlist
• https://www.steamgifts.com/giveaways/search?type=group
  using the "&" symbol as I have shown above (wishlist&copy_min, wishlist&level_min etc.), it seems that the site doesn't recognize the research and puts you back at its first page.

Is there a search string that I'm not able to find or is this impossible to obtain?
Thanks guys! :)
