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