Perhaps you should try some spelling variations:
entr » entro, ent, engr
entry » entroy, enty, engry
entra » entroa, enta, engra, extra, intra
entre » entroe, ente, engre
entree » entroee, entee, engree
entrees » entroees, entees, engrees
entropie » entroopie, entopie, engropie, entropy
'acteurs » 'facteurs, 'auteurs, 'amateurs

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