• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ly nang xa hoi. hieu ve ((((cham luc) OR (chat lua))) or (cham soc)) vay doanh van cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly nang xa hoi. hieu ve ((((cham luc) OR (chat lua))) OR (cham soc)) vay doanh van cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly nang xa hoi. hieu ve ((((cham luc) OR (chat lua))) or (cham soc)) vay doanh van cua tre*".
