Crawling using Storm Crawler

Question

We are trying to implement Storm Crawler to crawl data. We have been able to find sub-links from an url but we want to get contents from those sublinks. I have not been able find much resources which would guide me how to get it? Any useful links/websites in this regard would be helpful. Thanks.

Answer 1

Getting Started , presentations and talks , as well as the various blog posts should be useful.

If the sublinks are fetched and parsed - which you can check in the logs, then the content will be available for indexing or storing eg as WARC. There is a dummy indexer which dumps the content to the console which can be taken as a starting point, alternatively there are resources for indexing the documents in Elasticsearch or SOLR. The WARC module can be used to store the content of pages as well.
