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