Perhaps you should try some spelling variations:
entr » entry, entre, entra
entrea » entryea, entreea, entraea, entrega, entreat, entrena
entrent » entryent, entreent, entraent, entrench
entropie » entryopie, entreopie, entraopie, entropy
entree » entryee, entreee, entraee
entryoe » entryyoe, entreyoe, entrayoe

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 (entrea OR entrent)) OR ((entropie OR entree) OR entryoe))('act" or 'acute").
• Removing quotes may allow a broader search: ((entr or (entrea or entrent)) or ((entropie or entree) or entryoe))('act or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "((entr or (entrea or entrent)) or ((entropie or entree) or entryoe))('act" or 'acute")*.
