• Performing a fuzzy search may retrieve terms with similar spellings: vu ((san ky) or (dan ky)) nang ma hoa. nhieu viec cac xuc va hanh ((hai cua) OR (hoi cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((san ky) OR (dan ky)) nang ma hoa. nhieu viec cac xuc va hanh ((hai cua) OR (hoi cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((san ky) or (dan ky)) nang ma hoa. nhieu viec cac xuc va hanh ((hai cua) OR (hoi cua)) te*".
