How different is this from the functionality already avaialable through
SpanQuery?

I’ve been trying to do semi-structured queries & query parsing. In other
words, you could have XML snippets mixed in with plain terms, e.g. a query like:
christmas tree
where you’re looking for a document with the terms “christmas” “tree” but also
some structured data about where (pract
