• Performing a fuzzy search may retrieve terms with similar spellings: tu ((san ky) or (dan ky)) lang xa hoi. hieu ((qua cham) OR (qua hai)) xuc van thinh le cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (dan ky)) lang xa hoi. hieu ((qua cham) OR (qua hai)) xuc van thinh le cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) or (dan ky)) lang xa hoi. hieu ((qua cham) OR (qua hai)) xuc van thinh le cua viet".
• Adding a wildcard symbol may retrieve word variants: tu ((san ky) or (dan ky)) lang xa hoi. hieu ((qua cham) OR (qua hai)) xuc van thinh le cua viet*.
