• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky danh cay phoi. ((hieu ve) OR (((hieu van) OR (hieu va)))) cam duc ban anh than cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky danh cay phoi. ((hieu ve) or (((hieu van) OR (hieu va)))) cam duc ban anh than cua tre~".
• Adding a wildcard symbol may retrieve word variants: su sach ky danh cay phoi. ((hieu ve) or (((hieu van) OR (hieu va)))) cam duc ban anh than cua tre*.
