> We would like to modified stored documents properties.  The method is to use IndexReader
to open all files, modified some fields, and copy the document via addDocument() of IndexWriter
to another index.  But all fields that are created using Field.Store.NO are no longer available
for searching.

> <%@ page language="java" import="org.apache.lucene.analysis.standard.StandardAnalyzer;"%>
> <%@ page language="java" import="org.apache.lucene.document.*;"%>

>     // create for testing
>     IndexWriter writer = new IndexWriter("/opt/wwwroot/351/Index/test", new StandardAnalyzer(),
true, IndexWriter.MaxFieldLength.LIMITED);
>     Document doc = new Document();
>     doc.add(new Field("A", "1234", Field.Store.NO , Field.Index.NOT_ANALYZED));
>     doc.add(new Field("B", "abcd", Field.Store.NO , Field.Index.NOT_ANALYZED));
>     writer.addDocument(doc);
>     writer.close();
>     // check ok
>     Query q = new TermQuery(new Term("A", "1234"));
>     Searcher s = new IndexSearcher("/opt/wwwroot/351/Index/test");
>     Hits h = s.search(q);
>     out.println("# of document found is " + h.length());        // it is ok
>     // update the document to change or remove a field
>     IndexReader r = IndexReader.open("/opt/wwwroot/351/Index/test");
