• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty hang cao hoc. hieu ((ve cham) OR (va cham)) luc va danh ((vi cua) OR (vai cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty hang cao hoc. hieu ((ve cham) or (va cham)) luc va danh ((vi cua) OR (vai cua)) te~".
• Adding a wildcard symbol may retrieve word variants: te sach ty hang cao hoc. hieu ((ve cham) or (va cham)) luc va danh ((vi cua) OR (vai cua)) te*.
