                 Key: LUCENE-1787
                 URL: https://issues.apache.org/jira/browse/LUCENE-1787
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Analysis
    Affects Versions: 2.9
            Reporter: Paul taylor


Standard Tokenzizer doesn't recognise I.B.M it requires it end with a dot i.e I.B.M. This
is particulary problematic if I.B.M is added tot the index, with the StandardAnalyser it will
get added as  IBM , a search for I.B.M will not match because I.B.M will be left as is, I
would expect a match in this scenario

I think it could be fixed by modifying the  grammar ACRONYM_DEP  in StandardTokenizerImpl.jflex
so that it also supports

{ALPHANUM} ("." {ALPHANUM})+

dot only required between each character, (I'm not familiar with jflex syntax )
