• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ((ly lang) OR (ly hang)) xa hoi. hieu ((va cam) OR (va cham)) xuc van dich doc cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ((ly lang) OR (ly hang)) xa hoi. hieu ((va cam) or (va cham)) xuc van dich doc cua te".
• Adding a wildcard symbol may retrieve word variants: vu sach ((ly lang) OR (ly hang)) xa hoi. hieu ((va cam) or (va cham)) xuc van dich doc cua te*.
