• Performing a fuzzy search may retrieve terms with similar spellings: va sac ky ((lang ha) or (lang van)) hoi. thien van ((cam tuc) OR (nam thuc)) va hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: va sac ky ((lang ha) OR (lang van)) hoi. thien van ((cam tuc) OR (nam thuc)) va hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "va sac ky ((lang ha) or (lang van)) hoi. thien van ((cam tuc) OR (nam thuc)) va hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: va sac ky ((lang ha) or (lang van)) hoi. thien van ((cam tuc) OR (nam thuc)) va hanh vi cua te*.
