• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((loai nang) OR (loai nam)) xa hoi. lieu va cam duc tan nhanh ((thai ca) OR (thai va)) viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((loai nang) OR (loai nam)) xa hoi. lieu va cam duc tan nhanh ((thai ca) or (thai va)) viet".
• Adding a wildcard symbol may retrieve word variants: tu sach ((loai nang) OR (loai nam)) xa hoi. lieu va cam duc tan nhanh ((thai ca) or (thai va)) viet*.
