Perhaps you should try some spelling variations:
entr » entre, entry, entro
entra » entrea, entrya, entroa, entre, entry, extra
entree » entreee, entryee, entroee
entreee » entreeee, entryeee, entroeee, entrees, entreel, entreebre
entropie » entreopie, entryopie, entroopie, entropy
'acter » 'acteur, 'actor, 'actes

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 entra) OR ((entree OR entreee) OR entropie))('acted OR 'acter).
• Adding a wildcard symbol may retrieve word variants: ((entr or entra) or ((entree or entreee) or entropie))('acted or 'acter)*.
