Perhaps you should try some spelling variations:
entr » entry, entra, entro
entre » entrye, entrae, entroe, entry
entropie » entryopie, entraopie, entroopie, entropy
entraopie » entryaopie, entraaopie, entroaopie, entropies, entropien
'acte » 'acted, 'actes, 'act

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