Perhaps you should try some spelling variations:
entr » entro, ent, engr
entra » entroa, enta, engra, extra, intra
entre » entroe, ente, engre
entry » entroy, enty, engry
entred » entroed, ented, engred, centred
entree » entroee, entee, engree

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