Perhaps you should try some spelling variations:
entr » entry, entro, ent
entre » entrye, entroe, ente, entry
entra » entrya, entroa, enta, entry, extra, intra
entropie » entryopie, entroopie, entopie, entropy
'acts" » 'act"

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