• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"phung thi que van. noi dung uoc mo\") OR (\"nhung thoi cua ban. boi dung hoc mot\"))~".
• Removing quotes may allow a broader search: (( phung thi que van. noi dung uoc mo ) OR ( nhung thoi cua ban. boi dung hoc mot ))~.
• Adding a wildcard symbol may retrieve word variants: (("phung thi que van. noi dung uoc mo") OR ("nhung thoi cua ban. boi dung hoc mot"))*.
