• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang ma hoi. hieu va ((cau phuc) OR (huu phuc)) van ((hanh de) or (hanh kem)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang ma hoi. hieu va ((cau phuc) OR (huu phuc)) van ((hanh de) OR (hanh kem)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang ma hoi. hieu va ((cau phuc) OR (huu phuc)) van ((hanh de) or (hanh kem)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang ma hoi. hieu va ((cau phuc) OR (huu phuc)) van ((hanh de) or (hanh kem)) cua tre*.
