• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) OR (sach y)) lang ha hoi. ((hieu van) or (hieu va)) lam xuc va danh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach y)) lang ha hoi. ((hieu van) OR (hieu va)) lam xuc va danh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach y)) lang ha hoi. ((hieu van) or (hieu va)) lam xuc va danh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) OR (sach y)) lang ha hoi. ((hieu van) or (hieu va)) lam xuc va danh vai cuu tre*.
