• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty hoang va hoi. ((hieu van) OR (hieu va)) cam ((luc van) OR (luoc van)) anh vinh cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty hoang va hoi. ((hieu van) or (hieu va)) cam ((luc van) OR (luoc van)) anh vinh cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty hoang va hoi. ((hieu van) or (hieu va)) cam ((luc van) OR (luoc van)) anh vinh cuu tre*.
