Perhaps you should try some spelling variations:
entr » entre, entry, entra
entroe » entreoe, entryoe, entraoe, entrou, entropie
entrare » entreare, entryare, entraare, entrar, entrance, kontrare
entraine » entreaine, entryaine, entraaine, entrainer, entrance, entrant

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