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