Be sure to use the same Analyzer when indexing and searching.

What happens is your Analyzer is indexing each characters as an individual Term, and then if you search with a different analyzer (IE WhiteSpaceAnalyzer) it searches for a Token containing all the specified characters in your Query.

To search for a sequence of characters like you want, you need to use the same Analyzer and have the QueryParser build a PhraseQuery with all the individual Tokens.

Some sample code of your indexing and searching routines would make it easier to help you.
