• Performing a fuzzy search may retrieve terms with similar spellings: ((theo ha) or (theo phap)) tinh - ((hanh tang) OR (hanh mang)) he khong cong tac tran cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo ha) OR (theo phap)) tinh - ((hanh tang) OR (hanh mang)) he khong cong tac tran cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo ha) or (theo phap)) tinh - ((hanh tang) OR (hanh mang)) he khong cong tac tran cau".
• Adding a wildcard symbol may retrieve word variants: ((theo ha) or (theo phap)) tinh - ((hanh tang) OR (hanh mang)) he khong cong tac tran cau*.
