Perhaps you should try some spelling variations:
entr » entry, entro, ent
entre » entrye, entroe, ente, entry
entrye » entryye, entroye, entye, entree
entra » entrya, entroa, enta, entry, extra, intra
entroe » entryoe, entrooe, entoe, entrou, entropie

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