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