Perhaps you should try some spelling variations:
entr » entry, entre, entro
entra » entrya, entrea, entroa, entry, entre, extra
entrya » entryya, entreya, entroya, entryas, entryway
entropie » entryopie, entreopie, entroopie
entropy » entryopy, entreopy, entroopy
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 ento) OR (entra OR entrya)) OR (entropie OR entropy))('act OR 'acts).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((entr or ento) or (entra OR entrya)) or (entropie or entropy))('act or 'acts)".
• Adding a wildcard symbol may retrieve word variants: (((entr or ento) or (entra OR entrya)) or (entropie or entropy))('act or 'acts)*.
