You first need to extract meta data from your document in Nutch and add these as fields to your Nutch documents. I never tried it but there are some discussions about `extracting meta data using nutch` on the internet. Once the fields are in Solr you can use them as facets with ease. > > In the example above, I want to specify manually that the meta name > "categories" is to be treated as a facet, but the content should be > dynamically used as categories. > > Does it make sense?
