Perhaps you should try some spelling variations:
entr » entry, entra, entro
entre » entrye, entrae, entroe, entry
entroe » entryoe, entraoe, entrooe, entrou
entropie » entryopie, entraopie, entroopie, entropy
'acte" » 'acted", 'actes", 'act"
'actd" » 'act", 'acts", 'acid"

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 (entre or entroe)) or entropie)(('acte" OR 'actd") or 'acute").
• Removing quotes may allow a broader search: ((entr or (entre or entroe)) or entropie)(('acte or 'actd ) or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "((entr or (entre or entroe)) or entropie)(('acte" or 'actd") or 'acute")*.
