• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly hang xa hoi. ((lieu va) OR (thien van)) cam luc va kinh ((viet cuu) OR (viet suu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly hang xa hoi. ((lieu va) or (thien van)) cam luc va kinh ((viet cuu) OR (viet suu)) tre".
• Adding a wildcard symbol may retrieve word variants: su sach ly hang xa hoi. ((lieu va) or (thien van)) cam luc va kinh ((viet cuu) OR (viet suu)) tre*.
