• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu ve cham ((luc ban) OR (duc tan)) ((hanh va) OR (hanh vi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ve cham ((luc ban) or (duc tan)) ((hanh va) OR (hanh vi)) cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ve cham ((luc ban) or (duc tan)) ((hanh va) OR (hanh vi)) cua tre*.
