• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tu ((xang xa) OR (mang xa)) hoi. ((hieu van) OR (lieu va)) cam truc va thanh va cua viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tu ((xang xa) or (mang xa)) hoi. ((hieu van) OR (lieu va)) cam truc va thanh va cua viet~".
• Adding a wildcard symbol may retrieve word variants: tu sach tu ((xang xa) or (mang xa)) hoi. ((hieu van) OR (lieu va)) cam truc va thanh va cua viet*.
