• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ho gia qua tieu chuan") OR ("ho gia luan tieu chuan"))) OR ((("pho giau qua tieu hoa") OR ("pho giac quan bieu cua"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ho gia qua tieu chuan\") OR (\"ho gia luan tieu chuan\"))) or (((\"pho giau qua tieu hoa\") or (\"pho giac quan bieu cua\"))))~".
• Removing quotes may allow a broader search: (((( ho gia qua tieu chuan ) OR ( ho gia luan tieu chuan ))) or ((( pho giau qua tieu hoa ) or ( pho giac quan bieu cua ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("ho gia qua tieu chuan") OR ("ho gia luan tieu chuan"))) or ((("pho giau qua tieu hoa") or ("pho giac quan bieu cua"))))*.
