• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) OR (thuat sach)) ly nang xa hoi. hieu va ((cam duc) or (cao duc)) ban phan lap cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuat sach)) ly nang xa hoi. hieu va ((cam duc) OR (cao duc)) ban phan lap cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (thuat sach)) ly nang xa hoi. hieu va ((cam duc) or (cao duc)) ban phan lap cua tu".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) OR (thuat sach)) ly nang xa hoi. hieu va ((cam duc) or (cao duc)) ban phan lap cua tu*.
