• Performing a fuzzy search may retrieve terms with similar spellings: ((((ho lieu) OR (so lieu))) or (thi kieu)) tinh - thanh trung va nang cong trinh toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((ho lieu) OR (so lieu))) OR (thi kieu)) tinh - thanh trung va nang cong trinh toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((ho lieu) OR (so lieu))) or (thi kieu)) tinh - thanh trung va nang cong trinh toan ban*".
