IndexReader getFieldNames()

[varun sood]

Hi All,
  Can someone please guide me on how to use IndexReader's
getFieldNames() method properly?
I want to get all the filed names in the index. Currently I am getitng
it via Document object but that not wt i want.
I am implementing the code below and what I get is a very long string
of characters.. perhaps equivalent to the number of records in the
index.

Collection c = ir.getFieldNames(IndexReader.FieldOption.ALL);
int i = 0;
while (c.iterator().hasNext()) {
    Field s = (Field) c.iterator().next();
    out.print(s.name());
    i++;
}

Thanks,
Varun.
