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", 'acts", 'ace"
'acted" » 'actesd", 'actsd", 'aced"

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 'act") OR 'acted") or 'acute").
• Removing quotes may allow a broader search: (((entr or entropie) or entrea) or entropie)((('acte OR 'act ) or 'acted ) or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "(((entr or entropie) or entrea) or entropie)((('acte" OR 'act") or 'acted") or 'acute")*.
