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