Perhaps you should try some spelling variations:
entr » entry, entre, entro
entra » entrya, entrea, entroa, entry, entre, extra
entropy » entryopy, entreopy, entroopy
'acte" » 'actes", 'act", 'acts"
'acted" » 'actesd", 'actd", 'actsd"

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 entra) or entropy)(('acte" OR 'acted") or 'acute").
• Removing quotes may allow a broader search: ((entr or entra) or entropy)(('acte or 'acted ) or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "((entr or entra) or entropy)(('acte" or 'acted") or 'acute")*.
