• Performing a fuzzy search may retrieve terms with similar spellings: toc cach tu tang cho hoc. hieu ve cac xuc van ((hanh di) or (hanh vi)) ((cua cau) OR (cua cac))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc cach tu tang cho hoc. hieu ve cac xuc van ((hanh di) OR (hanh vi)) ((cua cau) OR (cua cac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc cach tu tang cho hoc. hieu ve cac xuc van ((hanh di) or (hanh vi)) ((cua cau) OR (cua cac))*".
