• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach thu lang van hoi. thi van lam luc va dinh ((((thi duc) OR (thinh duc))) OR (thi dua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach thu lang van hoi. thi van lam luc va dinh ((((thi duc) OR (thinh duc))) or (thi dua)) tre".
• Adding a wildcard symbol may retrieve word variants: thu sach thu lang van hoi. thi van lam luc va dinh ((((thi duc) OR (thinh duc))) or (thi dua)) tre*.
