What you're describing here is web mining, not web crawling. You want to extract price data from web pages, and put that into a specific field in Solr. To do that using Nutch, you'd need to write custom plug-ins that know how to extract the price from a page, and add that as a custom field to the crawl results. The above is a topic for the Nutch mailing list, since Solr is just a downstream consumer of whatever Nutch provides. -- Ken > On Sep 12, 2011 9:06 AM, "Erick Erickson [via Lucene]" < > ml-node+s472066n3328340...@n3.nabble.com> wrote: >> >> >> Nope, there's nothing in Solr that crawls anything, you have to feed >> documents in yourself from the websites. >> >> Or, look at the Nutch project, see: http://nutch.apache.org/about.html >> >> which is designed for this kind of problem. >> >> Best >> Erick >> >> On Sun, Sep 11, 2011 at 8:53 PM, dpt9876 <daninthetrop...@gmail.com> > wrote: >>> Hi all, >>> I am wondering if Solr will do the following for a project I am working > on. >>> I want to create a search engine with facets for potentially hundreds of >>> websites. >>> Similar to say crawling amazon + buy.com + ebay and someone can search > these >>> 3 sites from my 1 website. >>> (I realise there are better ways of doing the above example, its for >>> illustrative purposes). >>> Eventually I would build that search crawl to index say 200 or 1000 >>> merchants. >>> Someone would come to my site and search for "digital camera". >>> >>> They would get results from all 3 indexes and hopefully dynamic facets eg >>> Price $100-200 >>> Price 200-300 >>> Resolution 1mp-2mp >>> >>> etc etc >>> >>> Can this be done on the fly? >>> >>> I ask this because I am currently developing webscrapers to crawl these >>> websites, dump that data into a db, then was thinking of tacking on a > solr >>> server to crawl my db. >>> >>> Problem with that approach is that crawling the worlds ecommerce sites > will >>> take forever, when it seems solr might do that for me?
