Perhaps you should try some spelling variations:
entr » entry, entre, entra
entroe » entryoe, entreoe, entraoe, entrou
entrepre » entryepre, entreepre, entraepre, entreprise, entreprend, entrepris
entree » entryee, entreee, entraee
entropie » entryopie, entreopie, entraopie
entropy » entryopy, entreopy, entraopy

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 ((entroe OR (entrepre OR entree)) OR (entropie OR entropy)))('act" or 'acute")*.
• Removing quotes may allow a broader search: (entr or ((entroe or (entrepre or entree)) or (entropie or entropy)))('act or 'acute )*.
