• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ang xa hoi. ((hieu van) OR (hieu va)) ((chat nuoc) OR (thoat nuoc)) va trinh vi cua tuc~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ang xa hoi. ((hieu van) or (hieu va)) ((chat nuoc) OR (thoat nuoc)) va trinh vi cua tuc~".
• Adding a wildcard symbol may retrieve word variants: te sach ty ang xa hoi. ((hieu van) or (hieu va)) ((chat nuoc) OR (thoat nuoc)) va trinh vi cua tuc*.
