• Performing a fuzzy search may retrieve terms with similar spellings: ((((tu sach) OR (thu sach))) or (su sach)) ky nang xa hoi. hieu ve cam xuc va hanh de va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sach) OR (thu sach))) OR (su sach)) ky nang xa hoi. hieu ve cam xuc va hanh de va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu sach) OR (thu sach))) or (su sach)) ky nang xa hoi. hieu ve cam xuc va hanh de va triet*".
