• If you are trying to use Boolean operators, they must be ALL CAPS: te sach huy duong xa hoi. hieu va ((cam luc) OR (cau luc)) va dinh ((lam cuu) OR (lam cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach huy duong xa hoi. hieu va ((cam luc) OR (cau luc)) va dinh ((lam cuu) or (lam cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach huy duong xa hoi. hieu va ((cam luc) OR (cau luc)) va dinh ((lam cuu) or (lam cua)) tre*.
