• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sac) OR (thu san)) ky dang ma hoi. hieu va co ((toc xa) or (toc ta)) hanh dao suu viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sac) OR (thu san)) ky dang ma hoi. hieu va co ((toc xa) OR (toc ta)) hanh dao suu viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sac) OR (thu san)) ky dang ma hoi. hieu va co ((toc xa) or (toc ta)) hanh dao suu viet".
• Adding a wildcard symbol may retrieve word variants: ((thu sac) OR (thu san)) ky dang ma hoi. hieu va co ((toc xa) or (toc ta)) hanh dao suu viet*.
