Perhaps you should try some spelling variations:
entr » entry, ent, engr
entra » entrya, enta, engra, entry, extra, intra
entro » entryo, ento, engro, entry, intro, enero
entre » entrye, ente, engre, entry
ente » ende, ent, enge

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 entro) OR (entre OR ente))'acute.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((entr or entra) or entro) or (entre OR ente))'acute".
• Adding a wildcard symbol may retrieve word variants: (((entr or entra) or entro) or (entre OR ente))'acute*.
