Browse API search 0 results for specific sellers?

[v00vcx]

I've tried dozens of different filters, this happens only with specific seller filters.

None of these return any results for me, i can't figure it out:
https://api.ebay.com/buy/browse/v1/item_summary/search?q=Kleid&filter=sellers:{harleylinn}
https://api.ebay.com/buy/browse/v1/item_summary/search?category_ids=0&filter=sellers:{harleylinn}

https://api.ebay.com/buy/browse/v1/item_summary/search?category_ids=260010&filter=sellers:{harleylin...

the same thing is happening with another seller as well,

https://api.ebay.com/buy/browse/v1/item_summary/search?category_ids=0&offset=0&filter=sellers:{corwi...

what am i doing wrong?

i think you must encode all filters:

&filter=sellers%3A%7Bharleylinn%7D

Oh i am encoding them actually, 
https://api.ebay.com/buy/browse/v1/item_summary/search?category_ids=0&offset=0&filter=sellers%3A%7Bh...
still 0 results for me, does it work for you?

even if i specify filters that directly match part of the item name and category, it will return 0 results for many sellers

The problem with harleylinn is the nature of the offers. These are auctions that aren't returned by default unless you explicitly specify otherwise:

From the API-DOC:
Note: Only listings where FIXED_PRICE (Buy It Now) is a buying option are returned by default. To retrieve listings that do not have FIXED_PRICE as a buying option, the buyingOptions filter can be used to retrieve those listings.

Note that an auction listing enabled with the Buy it Now feature will initially show AUCTION and FIXED_PRICE as buying options, but if/when that auction listing receives a qualifying bid, only AUCTION remains as a buying option. If this happens, the buyingOptions filter would need to be used to retrieve that auction listing.
