• Performing a fuzzy search may retrieve terms with similar spellings: theo ((tieu sang) OR (tieu dung)) - thanh ((tung pham) or (tieng phap)) thong cong san chuan chau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu sang) OR (tieu dung)) - thanh ((tung pham) OR (tieng phap)) thong cong san chuan chau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu sang) OR (tieu dung)) - thanh ((tung pham) or (tieng phap)) thong cong san chuan chau".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu sang) OR (tieu dung)) - thanh ((tung pham) or (tieng phap)) thong cong san chuan chau*.
