• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((hanh nang) OR (anh nang)) cua nhung ((hong van) OR (thong van)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((hanh nang) or (anh nang)) cua nhung ((hong van) OR (thong van)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((hanh nang) or (anh nang)) cua nhung ((hong van) OR (thong van)) toan tap*.
