Perhaps you should try some spelling variations:
entr » entry, entra, entro
entre » entrye, entrae, entroe, entry
entrye » entryye, entraye, entroye, entree
entrepren » entryepren, entraepren, entroepren, entrypren, entreprend, entrepre, entrepris, entrepreen, entreren, entreprisen
entrepr » entryepr, entraepr, entroepr, entrypr, entrepre, entrer, entrepris
entropy » entryopy, entraopy, entroopy

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 entrye)) OR ((entrepren OR entrepr) OR entropy))('act OR 'acts).
• Adding a wildcard symbol may retrieve word variants: ((entr or (entre or entrye)) or ((entrepren or entrepr) or entropy))('act or 'acts)*.
