• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - hanh ((trinh cua) OR (trinh quan)) dong cong ((dan than) OR (van than)) tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - hanh ((trinh cua) OR (trinh quan)) dong cong ((dan than) or (van than)) tap".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - hanh ((trinh cua) OR (trinh quan)) dong cong ((dan than) or (van than)) tap*.
