• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ((thu tang) OR (thu hang)) ho hoi. hieu ve cham xu va danh ((vi cua) OR (de cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ((thu tang) OR (thu hang)) ho hoi. hieu ve cham xu va danh ((vi cua) or (de cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: vu sach ((thu tang) OR (thu hang)) ho hoi. hieu ve cham xu va danh ((vi cua) or (de cua)) tre*.
