• If you are trying to use Boolean operators, they must be ALL CAPS: thu xach tay ((lang xa) OR (dang xay)) hoi. hieu van cam xuc ca dan ((thi duc) OR (thi du)) tien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu xach tay ((lang xa) or (dang xay)) hoi. hieu van cam xuc ca dan ((thi duc) OR (thi du)) tien".
• Adding a wildcard symbol may retrieve word variants: thu xach tay ((lang xa) or (dang xay)) hoi. hieu van cam xuc ca dan ((thi duc) OR (thi du)) tien*.
