• If you are trying to use Boolean operators, they must be ALL CAPS: (((("pho gian dan tien thu") OR ("pho gian van tien thu"))) OR ((((("pho cap qua tiep cua") OR ((("pho cap cuu triet cua") OR ("pho tap cua triet cua"))))) OR ((((("pham sach luan dieu cua") OR ("pham sach luan tieu cua"))) OR ("pho sach luan dieu tra"))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"pho gian dan tien thu\") OR (\"pho gian van tien thu\"))) or (((((\"pho cap qua tiep cua\") or (((\"pho cap cuu triet cua\") or (\"pho tap cua triet cua\"))))) or (((((\"pham sach luan dieu cua\") or (\"pham sach luan tieu cua\"))) or (\"pho sach luan dieu tra\"))))))~".
• Removing quotes may allow a broader search: (((( pho gian dan tien thu ) OR ( pho gian van tien thu ))) or ((((( pho cap qua tiep cua ) or ((( pho cap cuu triet cua ) or ( pho tap cua triet cua ))))) or ((((( pham sach luan dieu cua ) or ( pham sach luan tieu cua ))) or ( pho sach luan dieu tra ))))))~.
