"Search" Content

I have been unable at times to find articles that I know to exist in old FWW's using  "Search". Today I was looking for an article by Carlyle Lynch on a Hepplewhite Chest of Drawers that I know is in Vol. 48 of FFW. Using both "Carlyle Lynch" and "Hepplewhite Chest of Drawers" in the search tool did not return any information on this article. Are there FWW articles not available for some reason? if so, what is the policy on what is and is not available.
