Perhaps you should try some spelling variations:
entr » entry, entre, entra
entrea » entryea, entreea, entraea, entrega, entreat, entrera
entrena » entryena, entreena, entraena, entrenar, entrent, entrega
entree » entryee, entreee, entraee
entroee » entryoee, entreoee, entraoee, entropie

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 (entrea OR entrena)) OR (entree OR entroee))('acute OR 'acutus).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((entr or (entrea OR entrena)) or (entree or entroee))('acute or 'acutus)".
• Adding a wildcard symbol may retrieve word variants: ((entr or (entrea OR entrena)) or (entree or entroee))('acute or 'acutus)*.
