---------------------------------------------------------------

                 Key: NUTCH-1197
                 URL: https://issues.apache.org/jira/browse/NUTCH-1197
             Project: Nutch
          Issue Type: Improvement
          Components: indexer
            Reporter: Andrzej Bialecki 
            Assignee: Andrzej Bialecki 
             Fix For: 1.4


In some cases it's useful to be able to add to every document sent to Solr a 
set of predefined fields with static values. This could be implemented on the 
Solr side (with a custom UpdateRequestProcessor), but it may be less cumbersome 
to add them on the Nutch side.

Example: let's say I have several Nutch configurations all indexing to the same 
Solr instance, and I want each of them to add its identifier as a field in all 
documents, e.g. "origin"="web_crawl_1", "origin"="file_crawl", 
"origin"="unlimited_crawl", etc...
