Keller Williams' claims do not check out. I have family in several areas of the midwest; and clicked onto your website to check out those areas. Even Billings, MT has nothing! There are no MLS listings displayed, only Keller Williams offices where you have to register on their office sites to get any info. Some states do not even have Keller Williams offices. "Verify before you believe" is true, here.

I'm not sure that an accurate site that has complete national coverage is really likely to exist. Odds are, it would be chock full of repeated properties, sold properties that should have been pulled off, things like that.
Realtor.com may be huge, but they certainly do not have every real estate listing.
Realtor.com does not have all the listings because not all brokerage firms download to Realtor.com. Keller Williams Realty, http://www.kw.com has data from across the nation because we have over 700 offices in the U.S. and Canada and the mls data from areas surrounding each of our offices is included at kw.com.
Good luck in your research. I'm curious what kind of data you are looking for. I have a lot of resources and may be able to point you in the right direction.
I can tell you a national site that truly has dependable real estate data from across America.
In the late 1990's Realtor.com had 95% of all listings. As politics and technology evolved many companies including Keller Williams and Windermere dropped out of realtor.com.
Keller Williams, http://www.kw.com , has created the first comprehensive national site. and Keller Williams has been working on this since the mid 1990's. Our website has now fully integrated mls systems from across the country. This has been an enormous task because different mls systems work differently and have different rules for sharing data.
KW.com is now the Number One search result on Google for anyone searching for real estate. I imagine there are small towns not included in our KW.com search solution, so in some small areas, you are best using a local broker's search.
The great advantage Keller Williams has is that it has been a Keller Williams strategy to have our agent websites as portals to their customers, and then to create a linked system for our over 70,000 Keller Williams Agent websites.
The Keller Williams' strategy has created local and North American search solutions. I see you are in Seattle, so if you want a great Seattle search, go to my website, http://www.karenmcknight.com . You will find a map based search if you click on the Property Search button on the left.
Good luck in your search. I am wondering if you are an investor. If so, I can tell you some markets that are getting great positive cash flow.

Most of the mls system in the Country do feed to Realtor.com, but most of the Country's mls systems are operated by the Board of Realtors. Seattle area is not, it is separately owned and operated. In much of the Country you have to join the Board of Realtors to have mls access and access to homes. Not so in the Seattle area. Consequently fewer real estate brokers and agents are members of the Realtor Organization here, than in many other parts of the Country.
Often the general public thinks "realtor" and real estate broker or agent are synonymous. They are not. Just as every tissue is not a "Kleenex", every agent is not a "realtor".
There is no single source that has all property for sale, including foreclosure property and For Sale by Owner properties. Better to use a brokerage site than Realtor .com in the area where you are looking, combined with Craigslist for For Sale by Owner properties.
For the Seattle area, the largest Brokerage which is Windermere does NOT send it's feed to Realtor.com. Neither does my company The Cascade Team, so Realtor.com coverage in the Seattle area is maybe around 50% complete.
