• If you are trying to use Boolean operators, they must be ALL CAPS: su sach hoa hoc thieu ((nhi cua) OR (ngai cua)) ets : nhung bo ((o vi) OR (so voi)) đai~.
• Adding a wildcard symbol may retrieve word variants: su sach hoa hoc thieu ((nhi cua) or (ngai cua)) ets : nhung bo ((o vi) or (so voi)) đai*.
