The purpose of [ Store.YES, Index.NO ] is to allow one to associate information with a document
without the waste of indexing that additional information in situations where that information
will never be used as serach criteria.
For example, in one of my applications I index the content of a properiatary library.  The
records in that library are always accessed by a positional index value.  As these positional
index values are of no use to the end-user of the application, but are needed internally to
retrieve the original library document, I associate the positional index with the Lucene document
as [ Store.YES, Index.NO ].

The question is that I used:
Field f = new Field("notindex","value",Store.YES,Index.NO);
and then use luke to view those index,and no field value can is there,but the field's value
is stored just not index_analyzed when construct the field.

Hope i am clear my question.
thanks
