Perhaps you should try some spelling variations:
entro » entry, entre, intro
entroepre » entryepre, entreepre, introepre, entrepre, entropie, entrepren
entropy » entrypy, entrepy, intropy
entra » entry, entre, extra
entrepr » entrepre, entrepris, entrepren
entrer » entree, entred

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