• Performing a fuzzy search may retrieve terms with similar spellings: ((su cac) or (tu cac)) ((ky trang) OR (ky trong)) xa hoi. hieu qua lap duc gia thanh hoa va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su cac) OR (tu cac)) ((ky trang) OR (ky trong)) xa hoi. hieu qua lap duc gia thanh hoa va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su cac) or (tu cac)) ((ky trang) OR (ky trong)) xa hoi. hieu qua lap duc gia thanh hoa va triet*".
