• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach tham)) dang xay hoi. hieu va ((cam luc) OR (cam xuc)) gia thanh vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (sach tham)) dang xay hoi. hieu va ((cam luc) OR (cam xuc)) gia thanh vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) or (sach tham)) dang xay hoi. hieu va ((cam luc) OR (cam xuc)) gia thanh vi cuu tre*.
