Hello Jim, yes, I am aware of the TermVector and MoreLikeThis stuff. I am presently mapping docvectors to these mechanisms and create term vectors myself from third-party text mining components.
However, it's not quite like the FAST docvectors. Particularily, the performance of MoreLikeThis queries based on TermVectors is suboptimal on large document sets, so a more efficient support of such retrievals in the Lucene kernel would be preferred.
