• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach tu)) lang xa hoi. hieu ve cam loc va danh ((hai cua) OR (thai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach tu)) lang xa hoi. hieu ve cam loc va danh ((hai cua) or (thai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) OR (sach tu)) lang xa hoi. hieu ve cam loc va danh ((hai cua) or (thai cua)) tre*.
