better text for failure
If a search for some particular string, and there is nothing found, there is no hint on the page i'm looking at that actually typed my search correctly, or that the keyserver interpreted it correctly. it just says "Error: Key not found"
The web interface would be better if it said "No key found for e-mail address foo@example.biz
" or "No key found matching fingerprint 1234567890123456789012345678901234567890
"
