My only point is, it's a whole lot easier to refactor your application to benefit from a different indexing engine than it is to export all of your data out of something, potentially remodel it to work in another. I suppose it all breaks down to how much work you're willing to invest to keep up with the Joneses (after all, you could just stay with Lucene), but I don't really see the argument of "XQuery is a standard". Just because it's a standard (vs. semi-ubiquitous API) doesn't mean it will have the best tools for a particular problem area. -Ross.
