• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ((ky tang) OR (ky dang)) xa hoi. hieu ve cham duc van thanh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su xac)) ((ky tang) or (ky dang)) xa hoi. hieu ve cham duc van thanh hai cua tre".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su xac)) ((ky tang) or (ky dang)) xa hoi. hieu ve cham duc van thanh hai cua tre*.
