Perhaps you should try some spelling variations:
"hedonic model" » "hedonica model", "hedonic modelo"
"hedonico model" » "hedonicao model", "hedonico modelo", "hedonica model", "hedonismo model", "edenico model"
"hedonicoa model" » "hedonicaoa model", "hedonicoa modelo", "hedonicaa model", "hedonismoa model", "edenicoa model", "hedonica model", "hedonista model"
"hedonicaa model" » "hedonicaaa model", "hedonicaa modelo", "hedonica model", "hedonista model"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("hedonic model") OR ((("hedonico model") OR ((("hedonicoa model") OR ("hedonicaa model"))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"hedonic model\") OR (((\"hedonico model\") OR (((\"hedonicoa model\") OR (\"hedonicaa model\"))))))*".
• Removing quotes may allow a broader search: (( hedonic model ) OR ((( hedonico model ) OR ((( hedonicoa model ) OR ( hedonicaa model ))))))*.
