PhraseQuery in lucene: PhraseQuery not searching on capitalized text such as ABC

Indexed text: I am learning ABC.

•  Suppose You indexed above text as TextField and using StandardAnalyzer for indexwriter
• doc.add(new TextField("fieldName", "I am learning ABC", Field.Strore.YES));
• You are trying to search with PhraseQuery like
• PhraseQuery pq=new PhraseQuery();
          pq.add(new Term("fieldName", "learning"));
          pq.add(new Term("fieldName", "ABC"));
          pq.setSlop(0);
• Search will not contain above document, because when textfield is indexed with the help of StandardAnalyzer terms are converted to lowercase and then indexed.
