Perhaps you should try some spelling variations:
entr » entry, entre, entra
entroe » entryoe, entreoe, entraoe, entrou
entropie » entryopie, entreopie, entraopie, entropy
entreoe » entryeoe, entreeoe, entraeoe, entree, entremes, entrepot

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 entropie) OR entreoe))('act" or 'acute").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(entr or ((entroe OR entropie) or entreoe))('act\" or 'acute\")".
• Removing quotes may allow a broader search: (entr or ((entroe OR entropie) or entreoe))('act or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "(entr or ((entroe OR entropie) or entreoe))('act" or 'acute")*.
