• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky sang) OR (ky nang)) lap hoi. hieu su chao ((xu ban) OR (xuc ban)) thanh va cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky sang) or (ky nang)) lap hoi. hieu su chao ((xu ban) OR (xuc ban)) thanh va cua te".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky sang) or (ky nang)) lap hoi. hieu su chao ((xu ban) OR (xuc ban)) thanh va cua te*.
