Perhaps you should try some spelling variations:
entr » entry, entre, ent
entro » entryo, entreo, ento, entry, entre, intro
entra » entrya, entrea, enta, entry, entre, extra
entropie » entryopie, entreopie, entopie, entrypie, entrepie, intropie
entropy » entryopy, entreopy, entopy, entrypy, entrepy, intropy
ento » onto, ent, endo

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 (entro OR ento)) OR entra) OR (entropie OR entropy))('act OR 'acts).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((entr or (entro OR ento)) or entra) or (entropie or entropy))('act or 'acts)".
• Adding a wildcard symbol may retrieve word variants: (((entr or (entro OR ento)) or entra) or (entropie or entropy))('act or 'acts)*.
