• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky ((nang cao) or (dang van)) hoi. hieu ve cam xuc van ((anh vi) OR (anh va)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((nang cao) OR (dang van)) hoi. hieu ve cam xuc van ((anh vi) OR (anh va)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((nang cao) or (dang van)) hoi. hieu ve cam xuc van ((anh vi) OR (anh va)) cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((nang cao) or (dang van)) hoi. hieu ve cam xuc van ((anh vi) OR (anh va)) cua triet*.
