> Project: Nutch
> Issue Type: Bug
> Components: indexer
> Affects Versions: 1.7
> Reporter: Sebastian Nagel
> Fix For: 2.3, 1.9

> Redirect targets are indexed using "representative URL"
> * in Fetcher repr URL is determined by URLUtil.chooseRepr() and stored in
> CrawlDatum (CrawlDb). Repr URL is either source or target URL of the redirect
> pair.
> * NutchField "url" is filled by basic indexing filter with repr URL
> * id field used as unique key is filled from url per solrindex-mapping.xml
> Deletion of redirects is done in IndexerMapReduce.reduce() by key which is
> the URL of the redirect source. If the source URL is chosen as repr URL a
> redirect target may get erroneously deleted.
> Test crawl with seed {{http://wiki.apache.org/nutch}} which redirects to
> {{http://wiki.apache.org/nutch/}}. DummyIndexWriter (NUTCH-1707) indicates
> that same URL is deleted and added:
> {code}
> delete http://wiki.apache.org/nutch
> add http://wiki.apache.org/nutch
> {code}
