• Performing a fuzzy search may retrieve terms with similar spellings: o ((chau tinh) OR (cua tinh)) - hanh ((trang cua) or (tang cua)) nhung cong dan than cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: o ((chau tinh) OR (cua tinh)) - hanh ((trang cua) OR (tang cua)) nhung cong dan than cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "o ((chau tinh) OR (cua tinh)) - hanh ((trang cua) or (tang cua)) nhung cong dan than cao".
• Adding a wildcard symbol may retrieve word variants: o ((chau tinh) OR (cua tinh)) - hanh ((trang cua) or (tang cua)) nhung cong dan than cao*.
