Perhaps you should try some spelling variations:
entr » entre, entra, entro
entry » entrey, entray, entroy
entroe » entreoe, entraoe, entrooe, entrou
entrooe » entreooe, entraooe, entroooe
entropie » entreopie, entraopie, entroopie, entropy

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 entry) OR (entroe OR (entrooe OR entropie)))('act" or 'acute").
• Removing quotes may allow a broader search: ((entr or entry) or (entroe or (entrooe or entropie)))('act or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "((entr or entry) or (entroe or (entrooe or entropie)))('act" or 'acute")*.
