Truncated	Reports whether the content length exceeds the summary length.			related returnType signatures methods/page/Summary bool PAGE.Truncated

There are three ways to define the content summary:

1. Let Hugo create the summary based on the first 70 words. You can change the number of words by setting the summaryLength in your site configuration.
2. Manually split the content with a <--more--> tag in markdown. Everything before the tag is included in the summary.
3. Create a summary field in front matter.

{{% note %}} The Truncated method returns false if you define the summary in front matter. {{% /note %}}

The Truncated method returns true if the content length exceeds the summary length. This is useful for rendering a "read more" link:

{{ range .Pages }}
  <h2><a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a></h2>
  {{ .Summary }}
  {{ if .Truncated }}
    <a href="{{ .RelPermalink }}">Read more...</a>
  {{ end }}
{{ end }}
