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