+Example:
+
+```go-html-template
+{{ $pages := .Site.RegularPages | first 50 }}+{{ $news := where $pages "Type" "news" | first 5 }}+{{ $blog := where $pages "Type" "blog" | first 5 }}+{{ $other := $pages | complement $news $blog | first 10 }}+```
+
+The above is an imaginary use case for the home page where you want to display different page listings in sections/boxes on different places on the page: 5 from `news`, 5 from the `blog` and then 10 of the pages not shown in the other listings, to _complement_ them.
