AnalyzingSuggester only matches by prefix, by design. You can try AnalyzingInfixSuggester, which is currently two alternative patches on https://issues.apache.org/jira/browse/LUCENE-4845
And please post back any feedback you have on the issue ... as the issue stands I don't think either approach will be committed any time soon.
