Why so complicated? Boosts do you no good,
you're only trying to find one document. Boosts influence
the score of documents in the ranking, but there's
only one.

I suspect if you looked at the debug form of the parsed query,
you'd find it pretty unexpected. You say it works  with
text fields, but I also suspect it's not doing quite what
you expect.

And it's all unnecessary and overly expensive anyway.
Just use a TermQuery. Term queries are very stupid and
do _no_ analysis of the term provided, they expect that
you already have done all that. They're very, very
efficient.

Best,
Erick
