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