• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ly) OR (sach lo)) hang xa hoi. ((hieu vu) OR (hieu ve)) cham tuc xa bang va cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ly) or (sach lo)) hang xa hoi. ((hieu vu) OR (hieu ve)) cham tuc xa bang va cua tre~".
• Adding a wildcard symbol may retrieve word variants: su ((sach ly) or (sach lo)) hang xa hoi. ((hieu vu) OR (hieu ve)) cham tuc xa bang va cua tre*.
