Perhaps you should try some spelling variations:
entro » entre, intro, enero
entropie » entrepie, intropie, eneropie, entropy
entry » entre
entryoe » entreoe
entra » entre, extra, intra
entrent » entrench

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