Perhaps you should try some spelling variations:
"terza rima" » "terra rima", "tera rima", "terz rima", "terza prima", "terza arima", "terza grima"
"terza rimas" » "terra rimas", "tera rimas", "terz rimas", "terza primas", "terza arimas", "terza grimas"
"tereza apgrima" » "tereza apgprima", "tereza apgarima", "tereza apggrima"
"terzo aproxima" » "terzo proxima", "terzo proximo"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("terza rima") OR ("terza rimas"))) OR ((("terzo aproxima") OR ("tereza apgrima"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"terza rima\") OR (\"terza rimas\"))) OR (((\"terzo aproxima\") OR (\"tereza apgrima\"))))*".
• Removing quotes may allow a broader search: (((( terza rima ) OR ( terza rimas ))) OR ((( terzo aproxima ) OR ( tereza apgrima ))))*.
