RE: How to loop through all the entries for a field

[Eric Advincula]

Question, now that i'm looping through the BookTitle, how can i also get the 
PageCount field that is part of the document.  So every BookTitle has a 
PageCount to signify the total number of pages per book.
Thanks
 
 

                reader = IndexReader.Open(Commons.Constants._FSDirectory);
                termEnum = reader.Terms(new Term("BookTitle", ""));
 

                while ((term = termEnum.Term()) != null)
                {
                    if (!term.Field().Equals("BookTitle"))
                        break;
 
                    map = new SearchResultMap();
                    map.Title = term.Text();
 
                    control.Items.Add(map);
 
                    termEnum.Next();
                }

nevermind I figured it out.  I did this:

                while ((term = termEnum.Term()) != null)
                {
                    if (!term.Field().Equals("BookTitle"))
                        break;

                    map = new SearchResultMap();
                    map.Title = term.Text();

                    control.Items.Add(map);

                    termEnum.Next();
                }

thanks for all the help

It works but continues even after the listing. 
How do you know if your on your last term?  I tried it and it does work but 
continues.  How do you know to check if its the last entry?

Thanks

Something like that?



      Lucene.Net.Index.IndexReader reader =
Lucene.Net.Index.IndexReader.Open(dir);

      Lucene.Net.Index.TermEnum tEnum = reader.Terms(new
Lucene.Net.Index.Term("BookTitle"));

      do

      {

            Lucene.Net.Index.Term t = tEnum.Term();

            Console.WriteLine(t.Text());

      } while (tEnum.Next());

I have a field in called BookTitle.  I want to loop through all the entries
without doing a search.  I just want to get the list of BookTitle's that is
in this field:



I tried IndexReader but MaxDocs() doesnt work because it returns everything
and I have other fields in their which is allot bigger.  



Thanks
