Perhaps you should try some spelling variations:
alte » alter, alten, alle
alterx » alterrx, altenrx, allerx, altere, altern, altera
alterrn » alterrrn, altenrrn, allerrn, alteren, altern, alteran
alterna » alterrna, altenrna, allerna, alternate, alternans
aller » allen, allem
allerx » allenx, allemx, allers, allern, allerh
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 ( ((vallex OR vallee) OR ((alterx OR allerx) OR alterrn)) OR alterna )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "( (alte or aller) or ( ((vallex or vallee) or ((alterx OR allerx) or alterrn)) or alterna ))".
• Adding a wildcard symbol may retrieve word variants: ( (alte or aller) or ( ((vallex or vallee) or ((alterx OR allerx) or alterrn)) or alterna ))*.
