Perhaps you should try some spelling variations:
entroy » entropy, entrou, entrophy
entrena » entrenar, entrent, entrega
entroe » entrou, entropie
'acte" » 'acted", 'actes", 'act"
'actd" » 'act", 'acts", 'acid"

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: "(((entre or (entry or entroy)) or entrena) or entroe)(('acte" OR 'actd") or 'acute").
• Removing quotes may allow a broader search: (((entre or (entry or entroy)) or entrena) or entroe)(('acte or 'actd ) or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "(((entre or (entry or entroy)) or entrena) or entroe)(('acte" or 'actd") or 'acute")*.
