• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"terza rima\") OR (((\"terza grimas\") OR (\"terza grimass\"))))) OR (\"terza arimass\"))".
• Removing quotes may allow a broader search: (((( terza rima ) OR ((( terza grimas ) OR ( terza grimass ))))) OR ( terza arimass )).
• Adding a wildcard symbol may retrieve word variants: (((("terza rima") OR ((("terza grimas") OR ("terza grimass"))))) OR ("terza arimass"))*.
