• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly tang van hoc. hieu ve cham ((tuc va) OR (truc va)) hanh ((di cua) OR (dieu cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly tang van hoc. hieu ve cham ((tuc va) OR (truc va)) hanh ((di cua) or (dieu cua)) te~".
• Adding a wildcard symbol may retrieve word variants: tu sach ly tang van hoc. hieu ve cham ((tuc va) OR (truc va)) hanh ((di cua) or (dieu cua)) te*.
