What's the way make a nutch index work like a the lucene index?

[Siva Sankara Reddy]

Hi there,
    I've created a temporary lucene index using
       $java org.apache.lucene.demo.IndexHTML -create -index {index-dir}
docs/
The index dir has just 3 files: _0.cfs segments_3 segments.gen
and it's working just fine with luceneweb.war (that comes with lucene
distribution)

       Where as the nutch index we have has the following 10 files in it:
_0.fdt  _0.fdx  _0.fnm  _0.frq  _0.nrm  _0.prx  _0.tii  _0.tis  segments_3
segments.gen
and it's giving  no results when I set  indexLocation  in
luceneweb/configuration.jsp to point to the nutch index

      What's the way make a nutch index work like a the lucene index (and
why the  .cfs file isn't present in the nutch index?)

Any help would be appreciated

Rgds,
Siva
