• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ((ky tang) OR (ky dang)) van hoi. hieu ve cham ((soc ba) or (hoc ban)) hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ((ky tang) OR (ky dang)) van hoi. hieu ve cham ((soc ba) OR (hoc ban)) hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ((ky tang) OR (ky dang)) van hoi. hieu ve cham ((soc ba) or (hoc ban)) hanh vi cua te*".
