Perhaps you should try some spelling variations:
entr » entry, entre, entro
entropy » entryopy, entreopy, entroopy
entra » entrya, entrea, entroa, entry, entre, extra
entrea » entryea, entreea, entroea, entrega, entreat, entrena
entrepre » entryepre, entreepre, entroepre, entreprise, entreprend, entrepris
entroyye » entryoyye, entreoyye, entrooyye, entropie

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 entropy) OR (entra OR entrea)) OR (entrepre OR entroyye))('act OR 'acts).
• Adding a wildcard symbol may retrieve word variants: (((entr or entropy) or (entra or entrea)) or (entrepre or entroyye))('act or 'acts)*.
