• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((vu nang) OR (va nang)) xa hoi. hieu va ((cac xuc) OR (chat xuc)) gia thanh dong cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((vu nang) or (va nang)) xa hoi. hieu va ((cac xuc) OR (chat xuc)) gia thanh dong cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((vu nang) or (va nang)) xa hoi. hieu va ((cac xuc) OR (chat xuc)) gia thanh dong cua tre*.
