Perhaps you should try some spelling variations:
entr » entry, entre, entra
entregar » entryegar, entreegar, entraegar, entrega, entrer, entreat
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 entregar) OR ((entropy OR entree) OR entryoe))('act" or 'acute").
• Removing quotes may allow a broader search: ((entr or entregar) or ((entropy or entree) or entryoe))('act or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "((entr or entregar) or ((entropy or entree) or entryoe))('act" or 'acute")*.
