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