• If you are trying to use Boolean operators, they must be ALL CAPS: (((("pho gian van tien thu") OR ("thoi gian lang tien thu"))) OR ((((("pho cap qua tap cua") OR ((("pho cay qua tap cua") OR ("pho cam qua tap cua"))))) OR ((("pham lan nhan dieu cua") OR ("khoa sach luan dieu tri"))))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"pho gian van tien thu\") or (\"thoi gian lang tien thu\"))) or (((((\"pho cap qua tap cua\") or (((\"pho cay qua tap cua\") OR (\"pho cam qua tap cua\"))))) or (((\"pham lan nhan dieu cua\") or (\"khoa sach luan dieu tri\"))))))*".
• Removing quotes may allow a broader search: (((( pho gian van tien thu ) or ( thoi gian lang tien thu ))) or ((((( pho cap qua tap cua ) or ((( pho cay qua tap cua ) OR ( pho cam qua tap cua ))))) or ((( pham lan nhan dieu cua ) or ( khoa sach luan dieu tri ))))))*.
