Perhaps you should try some spelling variations:
entra » entre, entry, extra
entrate » entrete, entryte, extrate, centrate, entrare, entrave
entropie » entropy
'acte" » 'acted", 'actes", 'act"
'actss" » 'acts", 'actes", 'actas"

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: "(entra or (entropie or entrate))(('acte" OR 'actss") or 'acute").
• Removing quotes may allow a broader search: (entra or (entropie or entrate))(('acte or 'actss ) or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "(entra or (entropie or entrate))(('acte" or 'actss") or 'acute")*.
