• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (thi lien)) xanh - hang ((hong quang) OR (thong quang)) dung cong ty phan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (thi lien)) xanh - hang ((hong quang) OR (thong quang)) dung cong ty phan cau".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (thi lien)) xanh - hang ((hong quang) OR (thong quang)) dung cong ty phan cau*.
