Perhaps you should try some spelling variations:
entr » entry, entro, ent
entra » entrya, entroa, enta, entry, extra, intra
entre » entrye, entroe, ente, entry
entrega » entryega, entroega, entega, entryga
entropy » entryopy, entroopy, entopy
entree » entryee, entroee, entee, entrye
entryoe » entryyoe, entroyoe, entyoe

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