• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sang ky) OR (dan ky)) lang ha hoi. lieu va cac xuc van ((hanh vi) OR (hanh kiem)) su triet.
• Adding a wildcard symbol may retrieve word variants: tu ((sang ky) or (dan ky)) lang ha hoi. lieu va cac xuc van ((hanh vi) or (hanh kiem)) su triet*.
