how to use multiple ListingType

[Ho52198]

Hello.
I am trying to use 2 ListingType filters with advanced search, but no luck so far.

The API state this "Note: Multiple listing type values can be specified for this filter.", but I can't way to implement this. If I try 2 values, only the last one is working.

This is especially helpful, when you try to combine Auction and AuctionWithBIN (if you want to list all auctions no matter do they have buy it now button or not). Auction itself is excluding all auctions with BIN.

Thank you
