Perhaps you should try some spelling variations:
entr » entry, entra, entro
entre » entrye, entrae, entroe, entry
entropie » entryopie, entraopie, entroopie, entropy
'acte" » 'actes", 'act", 'acts"
'acted" » 'actesd", 'actd", 'actsd"
'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 entropie)(('acte" or ('acted" OR 'actd")) or 'acute").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((entr or entre) or entropie)(('acte\" or ('acted\" OR 'actd\")) or 'acute\")".
• Removing quotes may allow a broader search: ((entr or entre) or entropie)(('acte or ('acted OR 'actd )) or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "((entr or entre) or entropie)(('acte" or ('acted" OR 'actd")) or 'acute")*.
