For us there is a mis-match between the collection screen and the search field. Search is only done in the active collection... which makes us spend loads of clicking to sell more than 1 item.
We created a collection with the best selling items. 32 items - nice and easy.
But customers always buys something outside the top 32... we use the search... no, because it only searches in the active collection :(
So we have to switch collection back to ALL before searching.
Perhaps some customers uses "search in collection only"(?) - so what about adding an option in the settings:
Search is always in all products YES / NO
