• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) or (sach uu)) nang x hoi. lieu va chat xuc van hanh vai ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach uu)) nang x hoi. lieu va chat xuc van hanh vai ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (sach uu)) nang x hoi. lieu va chat xuc van hanh vai ((cua triet) OR (su triet))".
