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

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