• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach thu) OR (sach tham)) nang xa hoi. ((hieu ve) OR (lieu va)) cham xuc va doanh van cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach thu) OR (sach tham)) nang xa hoi. ((hieu ve) or (lieu va)) cham xuc va doanh van cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach thu) OR (sach tham)) nang xa hoi. ((hieu ve) or (lieu va)) cham xuc va doanh van cua tre*.
