Subfetches allow you to use content from other URLs to populate
the current URL's record. We may have a site about articles, where
each article has a web page describing the article, and a link to a
PDF of the actual article. We'd like searches that match article
contents to take us to the web page, not the article PDF itself.
If the web page has a meta header called "pdfLink" with a URL to the article PDF, we can use the body of the PDF as a replacement for the web page's body with two Data from Field rules like this:
REX Search - (Empty)
Replace - (Empty)
From Field - Meta Field ->
From Meta Field - pdfLink
To Field - Subfetch
REX Search - .+
Replace - (Empty)
From Field - Text
From Meta Field - (Empty)
To Field - Body
The Subfetch Data from Field rule fetches the URL specified in
the pdfLink header. While this grabs the PDF, it doesn't
change anything on its own. We then pull from the PDF's text output,
and use that as the Body of the current web page.
