If you are in Ebay australia and trype in Latvia in the search bar it shows approximately1,600 items, That is for the default location. Change the location to worldwide and you see approx 10,000 items.The default category is Latvia. Why? You can change the default to "all categories". But why should you have to do it manually? If you type in another Country name such as Australia it uses all categories as a default.

Change to US Ebay and it will show 140,000 items with the default being all categories.

Until a month ago the search  numbers were similar for the Ebay Australia and US Eaby but not any more. Why the change?
