• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y ((nang xa) OR (dang xay)) hoi. hieu va ((cao duc) OR (cao suc)) va thanh lai cua tre.
• Adding a wildcard symbol may retrieve word variants: thu sach y ((nang xa) or (dang xay)) hoi. hieu va ((cao duc) or (cao suc)) va thanh lai cua tre*.
