• Performing a fuzzy search may retrieve terms with similar spellings: vu sach tu ((nang xa) OR (nang ma)) hoi. hieu ((va cam) or (va cao)) xuc van hanh hai chau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach tu ((nang xa) OR (nang ma)) hoi. hieu ((va cam) OR (va cao)) xuc van hanh hai chau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach tu ((nang xa) OR (nang ma)) hoi. hieu ((va cam) or (va cao)) xuc van hanh hai chau treo*".
