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