> Indexer doesn't consider linkdb when calculating boost value
> ------------------------------------------------------------
>
> Key: NUTCH-267
> URL: https://issues.apache.org/jira/browse/NUTCH-267
> Project: Nutch
> Issue Type: Bug
> Components: indexer
> Affects Versions: 0.8
> Reporter: Chris Schneider
> Priority: Minor
>
> Before OPIC was implemented (Nutch 0.7, very early Nutch 0.8-dev), if
> indexer.boost.by.link.count was true, the indexer boost value was scaled
> based on the log of the # of inbound links:
> if (boostByLinkCount)
> res *= (float)Math.log(Math.E + linkCount);
> This is no longer true (even before Andrzej implemented scoring filters).
> Instead, the boost value is just the square root (or some other scorePower)
> of the page score. Shouldn't the invertlinks command, which creates the
> linkdb, have some affect on the boost value calculated during indexing
> (either via the OPICScoringFilter or some other built-in filter)?
