• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach v) or (sach va)) nang x hoi. hieu qua tham soc va ((danh dien) OR (danh kien)) cuc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach va)) nang x hoi. hieu qua tham soc va ((danh dien) OR (danh kien)) cuc tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) or (sach va)) nang x hoi. hieu qua tham soc va ((danh dien) OR (danh kien)) cuc tre*".
