• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) or (thuat lanh)) ky nang xa hoi. hieu va cam ((truc va) or (tuc xa)) hanh ki su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuat lanh)) ky nang xa hoi. hieu va cam ((truc va) OR (tuc xa)) hanh ki su triet.
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (thuat lanh)) ky nang xa hoi. hieu va cam ((truc va) or (tuc xa)) hanh ki su triet*.
