• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky nang x hoi. thien van bac nuoc ((((va dang) OR (van dang))) or (va nang)) thai hoa viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang x hoi. thien van bac nuoc ((((va dang) OR (van dang))) OR (va nang)) thai hoa viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky nang x hoi. thien van bac nuoc ((((va dang) OR (van dang))) or (va nang)) thai hoa viet".
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang x hoi. thien van bac nuoc ((((va dang) OR (van dang))) or (va nang)) thai hoa viet*.
