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