• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (((v nang) OR (vu nang)))) xa hoi. hieu va chat luc van dang hai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) or (((v nang) OR (vu nang)))) xa hoi. hieu va chat luc van dang hai cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) or (((v nang) OR (vu nang)))) xa hoi. hieu va chat luc van dang hai cua tre*.
