• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"phung thi quan van. biet the hien cam xuc\") OR (\"phung thi quan luan. biet the hien cam xuc\"))~".
• Removing quotes may allow a broader search: (( phung thi quan van. biet the hien cam xuc ) OR ( phung thi quan luan. biet the hien cam xuc ))~.
• Adding a wildcard symbol may retrieve word variants: (("phung thi quan van. biet the hien cam xuc") OR ("phung thi quan luan. biet the hien cam xuc"))*.
