I am trying to save raw content and other information such as outlinks to Solr. I know Nutch2 doesn't do this, So I am trying to make some code change in Nutch2(a nutch IndexingFilter plugin later).
Checked Nutch2 code, seems we can add extra fields we need into Collection<WebPage.Field> FIELDS, Nutch2 uses Gora to run a query and add the value into Webpage instance. If I add FIELDS.add(WebPage.Field.CONTENT)(just for a test); in DbUpdaterJob, it works, in DbUpdateMapper I can see the value of content field in Webpage instance.. But if I can FIELDS.add(WebPage.Field.CONTENT) into IndexerJob, it doesn't work, still no content in webpage instance of IndexerMapper.map method. Could anyone provide me suggestion how to read value of extra fields from underlying datastore in IndexerJob/IndexerMapper? Thanks very much. -- View this message in context: http://lucene.472066.n3.nabble.com/How-to-ask-Nutch-to-get-value-of-extra-fields-in-IndexerJob-IndexerMapper-tp4083376.html Sent from the Nutch - User mailing list archive at Nabble.com.
