• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ly) OR (sach ty)) vang xa hoi. hieu ve chat soc va danh ((van chu) OR (van chat)) tre~.
• Adding a wildcard symbol may retrieve word variants: thu ((sach ly) or (sach ty)) vang xa hoi. hieu ve chat soc va danh ((van chu) or (van chat)) tre*.
