could expand a bit more the code? at least i wan to see where you
instantiate the analyzer, where you open the writer, what is the term you
use as key for update the document and how you create the document fields
also, for discard another kind of problems and isolate the problem, you can
make something like this in pseudocode:

Create a new index
add 1 document (with just 1 indexed, stored and tokenized field containing
"Z123456")
close index
open index
search document
close

and test if it works, if don't, post your code and we will see what is
happening.
