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
entreopie » entreeopie, entryeopie, entroeopie, entropies, entropien, entrepre
'acters » 'acteurs, 'acter

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 OR entreopie)))('acted OR 'acters).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((entr or entra) or ((entree or entreee) or (entropie OR entreopie)))('acted or 'acters)".
• Adding a wildcard symbol may retrieve word variants: ((entr or entra) or ((entree or entreee) or (entropie OR entreopie)))('acted or 'acters)*.
