• Performing a fuzzy search may retrieve terms with similar spellings: huu phach van quang va hoi. hieu ((ve cam) OR (va cam)) ((quoc ban) or (quoc bao)) hanh vi su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: huu phach van quang va hoi. hieu ((ve cam) OR (va cam)) ((quoc ban) OR (quoc bao)) hanh vi su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "huu phach van quang va hoi. hieu ((ve cam) OR (va cam)) ((quoc ban) or (quoc bao)) hanh vi su triet".
• Adding a wildcard symbol may retrieve word variants: huu phach van quang va hoi. hieu ((ve cam) OR (va cam)) ((quoc ban) or (quoc bao)) hanh vi su triet*.
