but ,as i said (asked) before, what would you do if two books have the =
same
title with different # of pages?

This is what I have:

                reader =3D IndexReader.Open(Commons.Constants._FSDirectory)=
;
                termEnum =3D reader.Terms(new Term("BookTitle", ""));
                while ((term =3D termEnum.Term()) !=3D null)
                {
                    if (!term.Field().Equals("Title"))
                        break;

                    if (term.Text() =3D=3D title)
                    {
                        termDocs =3D reader.TermDocs(term);
                       =20
                        result =3D true;
                        break;
                    }

                    termEnum.Next();
                }

But i'm not sure what to do with termDocs to get the information contained
in PageCount.  The pages vary from book to book.

Thanks

You can use "Lucene.Net.Index.TermDocs tDocs =3D  reader.TermDocs(term)"  =
in
your loop.

DIGY

PS: Another Question: How many pages does the book "T1" have?

Title    : T1
Author   : A1
#ofPages : 100
Publisher: P1

Title    : T1
Author   : A2
#ofPages : 200
Publisher: P1

Title    : T1
Author   : A1
#ofPages : 102
Publisher: P2
