• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) xanh - thanh trung cua thong ((trong san) OR (thong va)) than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) xanh - thanh trung cua thong ((trong san) or (thong va)) than cap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) xanh - thanh trung cua thong ((trong san) or (thong va)) than cap*.
