Michael McCandless created LUCENE-4821:
------------------------------------------

             Summary: AnalyzingSuggester should use end() offset to decide if last token ended or not
                 Key: LUCENE-4821
                 URL: https://issues.apache.org/jira/browse/LUCENE-4821
             Project: Lucene - Core
          Issue Type: Improvement
          Components: modules/spellchecker
            Reporter: Michael McCandless
            Assignee: Michael McCandless
             Fix For: 5.0, 4.3
         Attachments: LUCENE-4821.patch

For example, today if you index "i love lucy" and "isla de muerta", and then you ask for suggestions for "i" and for "i " (space after the i) you'll get the same results.

But if we use the ending offset, we can determine (I think?) that there were non-token characters after the last token, so that "i " would only suggest "i love lucy".
