• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((((chieu sach) OR (chiet tach))) OR (chieu sang)) - anh quang tran quang dung lap doan tap~.
• Adding a wildcard symbol may retrieve word variants: doi ((((chieu sach) or (chiet tach))) or (chieu sang)) - anh quang tran quang dung lap doan tap*.
