• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty hang tai hoi. hieu ve cham ((soc ban) OR (coc ban)) thanh lap ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty hang tai hoi. hieu ve cham ((soc ban) OR (coc ban)) thanh lap ((cua tre) or (cua te))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty hang tai hoi. hieu ve cham ((soc ban) OR (coc ban)) thanh lap ((cua tre) or (cua te))*.
