• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sac ky nang xa hoi. hieu va cam ((luc ban) or (cuu ban)) ((thanh ve) OR (thanh va)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sac ky nang xa hoi. hieu va cam ((luc ban) OR (cuu ban)) ((thanh ve) OR (thanh va)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sac ky nang xa hoi. hieu va cam ((luc ban) or (cuu ban)) ((thanh ve) OR (thanh va)) cua triet".
• Adding a wildcard symbol may retrieve word variants: thuoc sac ky nang xa hoi. hieu va cam ((luc ban) or (cuu ban)) ((thanh ve) OR (thanh va)) cua triet*.
