Perhaps you should try some spelling variations:
entr » entry, entre, entro
entra » entrya, entrea, entroa, entry, entre, extra
entree » entryee, entreee, entroee
entreel » entryeel, entreeel, entroeel, entrees, entremes
entropie » entryopie, entreopie, entroopie, entropy
entroopie » entryoopie, entreoopie, entrooopie, entropies, entropic, entropien
'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 entreel) OR (entropie OR entroopie)))('acted OR 'acters).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((entr or entra) or ((entree or entreel) or (entropie OR entroopie)))('acted or 'acters)".
• Adding a wildcard symbol may retrieve word variants: ((entr or entra) or ((entree or entreel) or (entropie OR entroopie)))('acted or 'acters)*.
