Perhaps you should try some spelling variations:
entr » entry, entro, ent
entre » entrye, entroe, ente, entry
entra » entrya, entroa, enta, entry, extra, intra
entroe » entryoe, entrooe, entoe, entrou
entropie » entryopie, entroopie, entopie, entropy
'acte" » 'acted", 'actes", 'act"

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 entra) OR (entroe OR entropie))('acte" or 'acute")*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(((entr or entre) or entra) or (entroe OR entropie))('acte\" or 'acute\")*".
• Removing quotes may allow a broader search: (((entr or entre) or entra) or (entroe OR entropie))('acte or 'acute )*.
