[jira] Updated: (NUTCH-514) Indexer should only index pages with fetch status SUCCESS

Doğacan Güney updated NUTCH-514:
--------------------------------

    Attachment: NUTCH-514.patch

A simple patch for the issue. Updates Indexer to check for STATUS_FETCH_SUCCESS.

I will let this patch stay here for a while. Is having 404 and 301 (and similar) pages in search results useful to anyone? Also, should we skip them in parser or filter them in indexer (as this patch does)?

> Currently if you parse during fetch, nutch only parses pages which are successfully (i.e, have a status STATUS_FETCH_SUCCESS). But, if you run parse as a seperate job, nutch parses pages like "404 not found"s or "301 moved"s. Since most of these can be successfully parsed these are indexed and show up in search results. 
> IMO, we should either somehow mark contents so that a separate parse doesn't output non-STATUS_FETCH_SUCCESS pages or we should filter them out in Indexer.
