Perhaps you should try some spelling variations:
entr » entry, entre, entra
entropie » entryopie, entreopie, entraopie, entropy
entrea » entryea, entreea, entraea, entrega, entreat, entrena
'acte" » 'actes", 'act", 'acts"
'acted" » 'actesd", 'actd", 'actsd"
'actesd" » 'actessd", 'actsd", 'actssd", 'actes"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: "(((entr OR entropie) OR entrea) OR entropie)(('acte" or ('acted" OR 'actesd")) or 'acute").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(((entr or entropie) or entrea) or entropie)(('acte\" or ('acted\" OR 'actesd\")) or 'acute\")".
• Removing quotes may allow a broader search: (((entr or entropie) or entrea) or entropie)(('acte or ('acted OR 'actesd )) or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "(((entr or entropie) or entrea) or entropie)(('acte" or ('acted" OR 'actesd")) or 'acute")*.
