• Performing a fuzzy search may retrieve terms with similar spellings: ((thu hai) or (thu nhap)) ky nang xa hoi. hieu van cam xuc tuan anh vi ((xu tren) OR (xa tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu hai) OR (thu nhap)) ky nang xa hoi. hieu van cam xuc tuan anh vi ((xu tren) OR (xa tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu hai) or (thu nhap)) ky nang xa hoi. hieu van cam xuc tuan anh vi ((xu tren) OR (xa tren))".
• Adding a wildcard symbol may retrieve word variants: ((thu hai) or (thu nhap)) ky nang xa hoi. hieu van cam xuc tuan anh vi ((xu tren) OR (xa tren))*.
