• If you are trying to use Boolean operators, they must be ALL CAPS: (((((((("romance language") OR ("romance languages"))) OR ("advanced language"))) OR ("performance language"))) OR ("romanic languages")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"romance language\") OR (\"romance languages\"))) or (\"advanced language\"))) or (\"performance language\"))) or (\"romanic languages\"))".
• Removing quotes may allow a broader search: (((((((( romance language ) OR ( romance languages ))) or ( advanced language ))) or ( performance language ))) or ( romanic languages )).
• Adding a wildcard symbol may retrieve word variants: (((((((("romance language") OR ("romance languages"))) or ("advanced language"))) or ("performance language"))) or ("romanic languages"))*.
