• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc thien) or (hoc thiet)) anh - hanh ((chinh van) OR (chinh ban)) nhuong cong van tuan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thien) OR (hoc thiet)) anh - hanh ((chinh van) OR (chinh ban)) nhuong cong van tuan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thien) or (hoc thiet)) anh - hanh ((chinh van) OR (chinh ban)) nhuong cong van tuan cau".
• Adding a wildcard symbol may retrieve word variants: ((hoc thien) or (hoc thiet)) anh - hanh ((chinh van) OR (chinh ban)) nhuong cong van tuan cau*.
