• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (vu sach)) ly hang xa hoi. lieu nha nam xuat va hanh vi ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ly hang xa hoi. lieu nha nam xuat va hanh vi ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) ly hang xa hoi. lieu nha nam xuat va hanh vi ((cua triet) OR (cua viet))".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (vu sach)) ly hang xa hoi. lieu nha nam xuat va hanh vi ((cua triet) OR (cua viet))*.
