Seems that should be working.

Having "number:1" as query text suggests that QueryParser.parse() was used
to get a query object, i.e. the query text is analyzed - which is
inconsistent with an UN_TOKENIZED field. Consider using TermQuery to avoid
tokenizing the query text:
    Query q = new TermQuery(new Term("number","1"));
However this cannot explain why no results are returned, since the string
"1" would generate the token "1" (well, "number:1") also with analysis.

Perhaps its the common problem of not closing indexWriter after adding the
doc or not re-opening searcher after closing the writer...
