Perhaps you should try some spelling variations:
entr » entre, entra, entro
entry » entrey, entray, entroy, entre
entrena » entreena, entraena, entroena, entrenar, entrent, entrega
entropie » entreopie, entraopie, entroopie, entropy
'acte" » 'acted", 'actes", 'acts"
'actd" » 'acts", 'acid", 'acta"

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