• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky dang van hoi. hieu ve cac duc tai lang dao ((cua triet) OR (((cua viet) OR (cua vat)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang van hoi. hieu ve cac duc tai lang dao ((cua triet) or (((cua viet) OR (cua vat))))".
• Adding a wildcard symbol may retrieve word variants: su sach ky dang van hoi. hieu ve cac duc tai lang dao ((cua triet) or (((cua viet) OR (cua vat))))*.
