• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((uu hang) OR (huu khang)) va hoa. hieu ve cac ((xuc van) or (luc van)) hanh de cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((uu hang) OR (huu khang)) va hoa. hieu ve cac ((xuc van) OR (luc van)) hanh de cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((uu hang) OR (huu khang)) va hoa. hieu ve cac ((xuc van) or (luc van)) hanh de cuu tre*".
