Perhaps you should try some spelling variations:
entr » entry, entra, entro
entre » entrye, entrae, entroe
entropie » entryopie, entraopie, entroopie
entropy » entryopy, entraopy, entroopy
entraine » entryaine, entraaine, entroaine, entrainer, entrance, entrant

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 entropy) OR entraine))('act" or 'acute").
• Removing quotes may allow a broader search: ((entr or entre) or ((entropie or entropy) or entraine))('act or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "((entr or entre) or ((entropie or entropy) or entraine))('act" or 'acute")*.
