A couple of questions:
1> I assume by "not returning any docs" you mean that you
never get into your while loop. Is that true?
2> I'm a little suspicious of the field labeled "id" and whether
it's at all possible that this is getting confused with the
internal Lucene doc ID. This is a wild shot in the dark
influenced by the fact that I'm working with Groovy where
property access is equivalent to get.....
3> What is the form of your unique key? If it's all numeric I
don't see a problem, but if it has any non-numeric
characters in it, then your analyzer will probably
lower-case the term wheres your term constructor
won't. Which would also explain why searching
would work.
If none of this is remotely helpful, could you post a few
examples of keys that work and those that don't?
