I’m looking into a search solution that will identify strings (company names) and use these strings for search and facets in Solr.

I’m new to Nutch and Solr so I wonder if this is best done in Nutch or in Solr. One solution would be to generate a Parser in Nutch that identifies the strings in question and then index the name of the company, later mapped to a Solr value. I’m not sure on how, but I guess this could also be done inside Solr directly from the text?

Does it make sense to do this string identification in Nutch or in Solr and is there some functionality in Solr or Nutch that could help me here?

Thanks.

    Nutch works with Solr by indexing the crawled data to Solr via the Solr HTTP API. You trigger the indexation by calling the solrindex command. See this page for details on how to setup this.

    To be able to extract the company names, I would add the necessary code in Solr. I would use a UpdateRequestProcessor. It allows to add an extra step in the indexing process to add extra fields in the document being indexed. Your UpdateRequestProcessor would be used to examine to document sent to Solr by Nutch, extract the company names from the text and add them as new fields in the document. Solr would them index the document + the fields that you add.
