LinkRank is a power iterative algorithm such as PageRank. It can be used incrementally and it very stable. Opic has trouble with increments. > * If I want to pass this data to solr during indexing , do I have to do > anything extra. The CrawlDB has a score field which is used to populate the boost field. With Opic this is added via the scoring filter. If you use the linkrank algorithm make sure you call it's scoreupdater tool, that writes the calculated scores back to the crawldb. > * If I want to sort the results from solr based on this data , which field > I should use? the boost field. > > Thanks, > Pratik >
