> NekoHTML parser use a method to extract all outlinks from the HTML page. It will extracts them from the HTML content based on the list of param defined in the method setConf(). Then this list of links will be truncated to be limit to the the maximum number of outlinks that we'll process for a page defined in nutch-default.xml (db.max.outlinks.per.page = 100 by default ) and finally it will be go through all urlfilter defined.
> Unfortunetly it can happen that the list of outlinks is more than 100, so it will truncated the list and could remove some relevant links.
> So I've added few options in the nutch-default.xml in order to enable/disable the extraction of specific HTML Tag links in this parser (SCRIPT, IMG, FORM, LINK).
