• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ty) OR (sach thu)) lang cac khoi. hieu ve cham cuc ban hanh ((vi cua) OR (doi cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ty) OR (sach thu)) lang cac khoi. hieu ve cham cuc ban hanh ((vi cua) or (doi cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ty) OR (sach thu)) lang cac khoi. hieu ve cham cuc ban hanh ((vi cua) or (doi cua)) tre*.
