An article I wrote on Yukon Full-Text Search has (finally!) been published on MSDN. Check it out:

I actually wrote the article a long time ago, and you would not believe how long it takes to run the whole thing through the wringer to get published.
I believe you will find what I wrote to be most satisfying. It covers:
- New FT features in Yukon
- A lay-person's overview of how search really works (this is probably helpful for non-db folks interested in search as well)
- Unadulterated, full-on 'disclosure' of our ranking algorithms
- Much more fun stuff...
Please read it and let me know what you think. As a side note, I should mention that I have taken on an exciting new role in Search in Microsoft, so I have moved on from the Yukon project. I can pass on your feedback to my successor, or you can just post it directly in the microsoft.public.sqlserver.fulltext newsgroup (I don't really get through there that often anymore).
Enjoy!
