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