Ah, but if I escape the "0" in the term constructor:
Term term2 = new Term("adzer", "\\0");It works. And then it works for a dash as well. Seems that to pass a search string to a queryParser, the "0" has to be escaped doubly:
searchString = "adzer: [# TO \\\\0]";
Just escaping with a double backslash does not work.
I still wonder though, if that is the desired behavior. It does not say on the page on the Lucene web site, that either "0" or "-" are special characters that need to be escaped.
Thanks for your time and for pointing me in the right direction.

Thanks for your reply.
If I do it manually:
Term term1 = new Term("adzer", "#"); Term term2 = new Term("adzer", "0"); Query myQuery = new RangeQuery(term1, term2, true); hits = searcher.search(myQuery);
I still get nothing. If I make the first term in the new RangeQuery call null:
Query myQuery = new RangeQuery(null, term2, true);
I get nothing. If, however I make the second term in the new RangeQuery call null:
Query myQuery = new RangeQuery(term1, null, true);
I get the results I expect.
Seems very strange.

However, if I create a range query that I would expect to find that

the quotes). As far as I can tell, this query string should find any
value in the adzer fields that starts with a "-".
Did you try building that query manually? Maybe even starting from null instead of #.
