• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach yu) OR (sach tu)) ((hang xa) OR (hoang ha)) hoi. hieu ve nham thuc xa thanh tai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach yu) OR (sach tu)) ((hang xa) or (hoang ha)) hoi. hieu ve nham thuc xa thanh tai cua tre~".
• Adding a wildcard symbol may retrieve word variants: so ((sach yu) OR (sach tu)) ((hang xa) or (hoang ha)) hoi. hieu ve nham thuc xa thanh tai cua tre*.
