How do I apply ranking to DocSearch via crawler?

Via the Crawler configuration: we provide an option to boost the weight of a page by adding a pageRank field to the extractor (see documentation) directly in the Crawler config.

You can programmatically detect the page you’d like to boost by either:

• Analyzing the URL that is being crawled
  
• The URL object is available in the parameters of the recordExtractor, see documentation
• Adding some extra informations in your DOM (e.g. a latest meta tag in the head), and retrieve it using the available cheerio instance
