• Performing a fuzzy search may retrieve terms with similar spellings: ((((tu sach) OR (tu cach))) or (thu sach)) ky lang xa hoi. hieu ve chat xuc va hanh vi lua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sach) OR (tu cach))) OR (thu sach)) ky lang xa hoi. hieu ve chat xuc va hanh vi lua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu sach) OR (tu cach))) or (thu sach)) ky lang xa hoi. hieu ve chat xuc va hanh vi lua tre".
• Adding a wildcard symbol may retrieve word variants: ((((tu sach) OR (tu cach))) or (thu sach)) ky lang xa hoi. hieu ve chat xuc va hanh vi lua tre*.
