• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty xang ma hoi. hieu va cham duc va ((hanh lai) or (hanh lam)) ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty xang ma hoi. hieu va cham duc va ((hanh lai) OR (hanh lam)) ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty xang ma hoi. hieu va cham duc va ((hanh lai) or (hanh lam)) ((cua triet) OR (cua viet))".
• Adding a wildcard symbol may retrieve word variants: thu sach ty xang ma hoi. hieu va cham duc va ((hanh lai) or (hanh lam)) ((cua triet) OR (cua viet))*.
