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