• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach tu)) hang xa hoi. hieu ((ve dao) OR (ve bao)) duc va thanh va cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) or (sach tu)) hang xa hoi. hieu ((ve dao) OR (ve bao)) duc va thanh va cua te".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ty) or (sach tu)) hang xa hoi. hieu ((ve dao) OR (ve bao)) duc va thanh va cua te*.
