Perhaps you should try some spelling variations:
alte » alter, alten, alle
alterx » alterrx, altenrx, allerx, altere, altera, alteri
altern » alterrn, altenrn, allern
alterrn » alterrrn, altenrrn, allerrn, alteren, alteran, alterin
alterna » alterrna, altenrna, allerna, alternate, alternans
aller » allem
allen » alle
vallex » valleix, valley, valles
vallee » valley

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: ( (alte OR (aller OR allen)) OR ( ((vallex OR vallee) OR ((alterx OR altern) OR alterrn)) OR alterna )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "( (alte or (aller or allen)) or ( ((vallex or vallee) or ((alterx OR altern) or alterrn)) or alterna ))".
• Adding a wildcard symbol may retrieve word variants: ( (alte or (aller or allen)) or ( ((vallex or vallee) or ((alterx OR altern) or alterrn)) or alterna ))*.
