indexing meta tags

(from github.com/maze13)
I crawl a site but the meta tags <meta name=“description” …/> and <meta name=“keywords” …/> are not indexed and I cannot find the values when I search for it. How can I set this up?

I’m using fess 13.3

You can specify it in fess_config.properties by XPath:

crawler.document.html.content.xpath=//BODY
