We'll have to post our experiences with it, but we noted recently that Footnote.com is allowing a test of it's advanced searches. They can be tried here:
Beta Test of Advanced Search at Footnote.com

It also appears that some of the searching issues that I had earlier on have been corrected, but I might have just gotten lucky. When I searched at Footnote.com on specific Virginia regiments from the American Revolution for specific words, I obtained results. I had not obtained them before. We'll be posting updates to this as time allows.
