I think this is interesting, but I wonder about the performance.
There are two main reasons  for using text retrieval, as I see it.
(1) for searching a large body of text significantly more quickly than
    with grep

(2) for kinds of search not otherwise possible, such as searches that
    span words, or that include stemming, synonyms or other morphological
    and linguistic analysis, or that include document structure or other
    "fielded" searches.

This sounds like an interesting proof of concept...
but if I am searching, say, five gigabytes of text, what
will happen?

Indexing speed is also an issue.

So I assume the main purpose of this tool is to experiment
with XPath/XQL, is that fair??

and yes, I'd like a copy!  thanks :-)
