• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. ((hieu van) OR (lieu va)) cac tuc van thanh ((van cua) OR (ban cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. ((hieu van) OR (lieu va)) cac tuc van thanh ((van cua) or (ban cua)) tre*".
