Solr extract data from the index to a XML file

We have the index files which are provided by the client and now want to reindex them by removing the duplicate documents

Solr deduplication

for this i have to read the data from the index and have to generate an XML file or CSV file and then index them with eliminating duplicates

(correct me if im wrong i didnt find any other way to do this)

I know this is possible using Lucene but i wanted to know how can i do this using solr

You can change the export format by setting the wt parameter to xml ...&wt=xml at you Solr query.

This will export the results to xml. So if you search for * you will get the full content - depending on the limit parameter.

http://wiki.apache.org/solr/CoreQueryParameters#wt

That will also work with csv: http://wiki.apache.org/solr/CSVResponseWriter
