There is problem with auto search. When I specify "available to country" option to specific,for example, Sweden, nothing can be found even if there is such items for shore, and I can found it searching directly in eBay.

The searches in AS are not as reliable/accurate as ebay's. You can use the following link to get a dialog going with a support person, but if I was in the advice giving business I'd advise you to use ebay's search.
