Perhaps you should try some spelling variations:
entro » entry, entre, intro
entroee » entryee, entreee, introee, entropie
entra » entry, entre, extra
'acutes » 'akutes, 'acutus, 'acutis
'akuten » 'akute

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 entra) OR entroee)('acute OR ('acutes OR 'akuten)).
• Adding a wildcard symbol may retrieve word variants: ((entro or entra) or entroee)('acute or ('acutes or 'akuten))*.
