Perhaps you should try some spelling variations:
entr » entry, entro, ent
entre » entrye, entroe, ente, entry
entra » entrya, entroa, enta, entry, extra, intra
entrepre » entryepre, entroepre, entepre, entrypre, entreprise, entreprend, entrepris
entryye » entryyye, entroyye, entyye
entroyye » entryoyye, entrooyye, entoyye, entropie
entropy » entryopy, entroopy, entopy

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