• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sai ky) OR (dai ly)) dang xa hoi. hieu va cham duc tuan dang thi ((duc tre) OR (duoc tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sai ky) or (dai ly)) dang xa hoi. hieu va cham duc tuan dang thi ((duc tre) OR (duoc tren))".
• Adding a wildcard symbol may retrieve word variants: su ((sai ky) or (dai ly)) dang xa hoi. hieu va cham duc tuan dang thi ((duc tre) OR (duoc tren))*.
