You should get back the stored value from the index as it was when you
added it. But depending on your analyzer, and your requirements, you
may not be able to search as you want.
Read up on analysis and how to use it or not use it for individual
fields, stored and/or indexed. Read Lucene in Action.
Post again with complete self-contained code, and details of what
is/isn't happening correctly, if you can't work it out.
