Perhaps you should try some spelling variations:
entr » entry, entra, entro
entre » entrye, entrae, entroe
entroe » entryoe, entraoe, entrooe, entrou
entrayoe » entryayoe, entraayoe, entroayoe, entrance, entraine, entrare
entropie » entryopie, entraopie, entroopie, entropy

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 entrayoe) OR entropie))('act" or 'acute").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((entr OR entre) or ((entroe or entrayoe) or entropie))('act\" or 'acute\")".
• Removing quotes may allow a broader search: ((entr OR entre) or ((entroe or entrayoe) or entropie))('act or 'acute ).
• Adding a wildcard symbol may retrieve word variants: "((entr OR entre) or ((entroe or entrayoe) or entropie))('act" or 'acute")*.
