[jira] Commented: (NUTCH-963) Add support for deleting Solr documents with STATUS_DB_GONE in CrawlDB (404 urls)

Markus Jelsma commented on NUTCH-963:
-------------------------------------

Thanks Claudio. I'll fix the formatting and add a command to the bin/nutch script. If there are no objections, i'd like to have this one included in the 1.3 release. Despite the fact it's not a bugfix, it is a very useful feature. Without it, users must either patch it manually or build their own deleter.

> When issuing recrawls it can happen that certain urls have expired (i.e. URLs that don't exist anymore and return 404).
> This patch creates a new command in the indexer that scans the crawldb looking for these urls and issues delete commands to SOLR.
