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