I don't see how it can be done without writing sax or dom code for each job board, it is non-maintainable if there are a lot of new job boards being crawled. Maybe I should use regex match? Then I just need to substitute the regex pattern for each job board without writing any new sax or dom code. But is regex pattern flexible enough for all job boards? Thanks.

If you can't find the pattern for each site leading to the job title how can you expect solr to?

If there are constantly new job boards being crawled, I don't think I can manually look for specific sequence of tags that leads to job title. Most of them don't even have class or id. There is no guarantee that the job title will be in the title tag, or header tag. Something else can be in the title. Should I do this in a class that extends IndexFilter in Nutch? Thanks. ________________________________ From: Dave Searle <dave.sea...@magicalia.com> To: "solr-user@lucene.apache.org" <solr-user@lucene.apache.org> Sent: Wed, July 21, 2010 8:42:55 AM Subject: RE: faceted search with job title You'd probably need to do some post processing on the pages and set up rules for each website to grab that specific bit of data. You could load the html into an xml parser, then use xpath to grab content from a particular tag with a class or id, based on the particular website -----Original Message----- From: Savannah Beckett [mailto:savannah_becket...@yahoo.com] Sent: 21 July 2010 16:38 To: solr-user@lucene.apache.org Subject: faceted search with job title Hi, I am currently using nutch to crawl some job pages from job boards. They are in my solr index now. I want to do faceted search with the job titles. How? The job titles can be in any locations of the page, e.g. title, header, content... If I use indexfilter in Nutch to search the content for job title, there are hundred of thousands of job titles, I can't hard code them all. Do you have a better idea? I think I need the job title in a separate field in the index to make it work with solr faceted search, am I right? Thanks.
