Perhaps you should try some spelling variations:
entr » entry, entre, entra
entrea » entryea, entreea, entraea, entrega, entrena, entrera
entreat » entryeat, entreeat, entraeat, entregat, entrenat, entrerat, entrent, entrepot
entropy » entryopy, entreopy, entraopy
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 entreat)) OR ((entropy OR entree) OR entryoe))('act" or 'acute").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((entr or (entrea OR entreat)) or ((entropy or entree) or entryoe))('act\" or 'acute\")".
• Removing quotes may allow a broader search: ((entr or (entrea OR entreat)) or ((entropy or entree) or entryoe))('act or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "((entr or (entrea OR entreat)) or ((entropy or entree) or entryoe))('act" or 'acute")*.
