Notacat,
A number of VS 2010 Beta 2 customers have asked why we did not deliver a Keyword Index as part of the new help system. We realize the importance of delivering a keyword index, but we were unable to deliver it in our first release. In this V1.0 release of help system, we first implemented an improved search capability in order to deliver a more familiar, consistent online and offline experience. We then implemented a keyword index feature based on our search catalog. Unfortunately, the results did not meet our quality bar and we determined that this feature would require more work than the Beta 2 timeline allowed. We are looking at implementing it for at future release.
In the meantime, the usage pattern we anticipate is that you'll search for the general concept using full text search and then refine your topic selection using the TOC and related topics. We did anticipate that there would be a period of adjustment for customers. Our hope is that you will try working with the new design and give us feedback that we can use to prioritize the features and fixes that our team delivers in later releases.
