Perhaps you should try some spelling variations:
"hedonico model" » "hedonismo model", "edenico model", "veronico model", "hedonico modelo"
"hedonica model" » "hedonica modelo", "hedonista model", "veronica model", "helenica model"
"helenico model" » "helenico modelo", "helenica model", "edenico model", "elenio model"
"helenismo model" » "helenismo modelo"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"hedonico model\") OR (((\"hedonica model\") OR (((\"helenico model\") OR (\"helenismo model\"))))))~".
• Removing quotes may allow a broader search: (( hedonico model ) OR ((( hedonica model ) OR ((( helenico model ) OR ( helenismo model ))))))~.
• Adding a wildcard symbol may retrieve word variants: (("hedonico model") OR ((("hedonica model") OR ((("helenico model") OR ("helenismo model"))))))*.
