Perhaps you should try some spelling variations:
entr » entry, entre, entra
entropie » entryopie, entreopie, entraopie, entropy
entreopie » entryeopie, entreeopie, entraeopie, entropies, entropien, entrepre
entrye » entryye, entreye, entraye, entree
intro » intra
etayo » etaye

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