Perhaps you should try some spelling variations:
entr » entry, entre, entra
entrea » entryea, entreea, entraea, entreat, entrera, entred
entrena » entryena, entreena, entraena, entrenar, entrent, entren
entrega » entryega, entreega, entraega
entropie » entryopie, entreopie, entraopie, entropy
entree » entryee, entreee, entraee
entryoe » entryyoe, entreyoe, entrayoe

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