Okay, I found the search engine. Without reposting address specifics, I still can't get it to work.
I can't get it to accept 98th street as 98, 98th, or ninety-eighth. I'd think the full zip code should be enough. But street name is a required field.
"Do not include Street Direction(N.,W.,SE.,etc) or Street Type(St.,Ave.,Ln.etc)"

Less then impressed with the site. Hard to find someone without all the information.
