Perhaps you should try some spelling variations:
entr » entry, entre, entra
entropie » entryopie, entreopie, entraopie, entropy
entraopie » entryaopie, entreaopie, entraaopie, entropies
entropien » entryopien, entreopien, entraopien, entropyn, entropies, entropion, entretien

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