Perhaps you should try some spelling variations:
entr » entry, entre, entra
entrey » entryey, entreey, entraey, entree, entred, entren
entrer » entryer, entreer, entraer, entree, entred
entrena » entryena, entreena, entraena, entrenar, entrent, entrega
entropie » entryopie, entreopie, entraopie, entropy
'acte » 'acted, 'actes, 'act
'actd » 'act, 'acts, 'acid

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 (entrey OR entrer)) OR entrena) OR entropie)(('acte OR 'actd ) OR 'acute ).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((entr or (entrey OR entrer)) or entrena) or entropie)(('acte or 'actd ) or 'acute )".
• Adding a wildcard symbol may retrieve word variants: (((entr or (entrey OR entrer)) or entrena) or entropie)(('acte or 'actd ) or 'acute )*.
