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
entreea » entryeea, entreeea, entroeea, entree, entrees, entrega
entrooepre » entryooepre, entreooepre, entroooepre, entrepre
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 entreea))) OR (entrooepre OR entroyye))('act OR 'acts).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((entr or entropy) or (entra or (entrea OR entreea))) or (entrooepre or entroyye))('act or 'acts)".
• Adding a wildcard symbol may retrieve word variants: (((entr or entropy) or (entra or (entrea OR entreea))) or (entrooepre or entroyye))('act or 'acts)*.
