Perhaps you should try some spelling variations:
entr » entry, entra, entro
entre » entrye, entrae, entroe, entry
entropie » entryopie, entraopie, entroopie, entropy
entrees » entryees, entraees, entroees, entryes, entree
entryoe » entryyoe, entrayoe, entroyoe

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