• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ly) OR (sach lo)) nang xa hoi. hieu vien cac xuc van ((hanh dai) OR (vanh dai)) cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ly) OR (sach lo)) nang xa hoi. hieu vien cac xuc van ((hanh dai) or (vanh dai)) cua tu*".
