• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky nang xa hoi. hieu ((ve cao) or (((vien cac) OR (vien dai)))) suc ca nhan tiep cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang xa hoi. hieu ((ve cao) OR (((vien cac) OR (vien dai)))) suc ca nhan tiep cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky nang xa hoi. hieu ((ve cao) or (((vien cac) OR (vien dai)))) suc ca nhan tiep cua tu".
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang xa hoi. hieu ((ve cao) or (((vien cac) OR (vien dai)))) suc ca nhan tiep cua tu*.
