• Performing a fuzzy search may retrieve terms with similar spellings: ((thuat san) OR (thuat lanh)) ky nang cao hoi. hieu ve cham lo ((va hanh) or (va danh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat san) OR (thuat lanh)) ky nang cao hoi. hieu ve cham lo ((va hanh) OR (va danh)) vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuat san) OR (thuat lanh)) ky nang cao hoi. hieu ve cham lo ((va hanh) or (va danh)) vi cua tre".
• Adding a wildcard symbol may retrieve word variants: ((thuat san) OR (thuat lanh)) ky nang cao hoi. hieu ve cham lo ((va hanh) or (va danh)) vi cua tre*.
