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 )
