• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach y)) nang cao hoi. hieu hien bach ((xuc va) OR (tuc va)) danh dau cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach y)) nang cao hoi. hieu hien bach ((xuc va) or (tuc va)) danh dau cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) OR (sach y)) nang cao hoi. hieu hien bach ((xuc va) or (tuc va)) danh dau cua tre*.
