-### Methods
+The `Related` method takes one argument which may be a `Page` or a options map. The options map have these options:
 
-Here is the list of "Related" methods available on a page collection such `.RegularPages`.
+indices
+: The indices to search in.
 
-#### .Related PAGE
+document
+: The document to search for related content for.
 
-Returns a collection of pages related the given one.
+namedSlices
+: The keywords to search for.
+
+fragments
+: Fragments holds a a list of special keywords that is used for indices configured as type "fragments". This will match the fragment identifiers of the documents.
+
+A fictional example using all of the above options:
 
 ```go-html-template
-{{ $related := site.RegularPages.Related . }}
+{{ $page := . }}
+{{ $opts := 
+  "indices" (slice "tags" "keywords")
+  "document" $page
+  "namedSlices" (slice (keyVals "tags" "hugo" "rocks") (keyVals "date" $page.Date))
+  "fragments" (slice "heading-1" "heading-2")
+}}
 ```
 
-#### .RelatedIndices PAGE INDICE1 [INDICE2 ...]
+{{% note %}}
+We improved and simplified this feature in Hugo 0.111.0. Before this we had 3 different methods: `Related`, `RelatedTo` and `RelatedIndicies`. Now we have only one method: `Related`. The old methods are still available but deprecated. Also see [this blog article](https://regisphilibert.com/blog/2018/04/hugo-optmized-relashionships-with-related-content/) for a great explanation of more advanced usage of this feature.

+## Index Content Headings in Related Content
 
-Returns a collection of pages related to a given one restricted to a list of indices.
+{{< new-in "0.111.0" >}}
 
-```go-html-template
-{{ $related := site.RegularPages.RelatedIndices . "tags" "date" }}
-```
+Hugo can index the headings in your content and use this to find related content. You can enable this by adding a index of type `fragments` to your `related` configuration:
 
-#### .RelatedTo KEYVALS [KEYVALS2 ...]
 
-Returns a collection of pages related together by a set of indices and their match.
+```toml
+[related]
+threshold    = 20
+includeNewer = true
+toLower      = false
+[[related.indices]]
+name        = "fragmentrefs"
+type        = "fragments"
+applyFilter = false
+weight      = 80
+```
 
-In order to build those set and pass them as argument, one must use the `keyVals` function where the first argument would be the `indice` and the consecutive ones its potential `matches`.
+* The `name` maps to a optional front matter slice attribute that can be used to link from the page level down to the fragment/heading level.
+* If `applyFilter`is enabled, the `.HeadingsFiltered` on each page in the result will reflect the filtered headings. This is useful if you want to show the headings in the related content listing:
 
 ```go-html-template
-{{ $related := site.RegularPages.RelatedTo ( keyVals "tags" "hugo" "rocks")  ( keyVals "date" .Date ) }}
+{{ $related := .Site.RegularPages.Related . | first 5 }}
+{{ with $related }}
+  <h2>See Also</h2>
+  <ul>
+    {{ range . }}
+      <li>
+        <a href="{{ .RelPermalink }}">{{ .Title }}</a>
+        {{ with .HeadingsFiltered }}
+          <ul>
+            {{ range . }}
+              {{ $link := printf "%s#%s" $.RelPermalink .ID }}
+              <li>
+                <a href="{{ $link }}">{{ .Title }}</a>
+              </li>
+            {{ end }}

 ## Configure Related Content
 
 Hugo provides a sensible default configuration of Related Content, but you can fine-tune this in your configuration, on the global or language level if needed.

 name
 :  The index name. This value maps directly to a page param. Hugo supports string values (`author` in the example) and lists (`tags`, `keywords` etc.) and time and date objects.
 
+type
+: {{< new-in "0.111.0" >}}. One of `basic`(default) or `fragments`.

+applyFilter
+: {{< new-in "0.111.0" >}}. Apply a `type` specific filter to the result of a search. This is currently only used for the `fragments` type.

 weight
 : An integer weight that indicates _how important_ this parameter is relative to the other parameters.  It can be 0, which has the effect of turning this index off, or even negative. Test with different values to see what fits your content best.
