Related Pages row when searching

[luciankt]

When the user searches for something in the search bar, a row may pop up below the search results with "Related Pages". For example, if someone searches "Stack", then the Queues would also pop up since they are related by being commonly-paired linear data structures.

What appears under which circumstances is up for debate and something to be discussed!

Being worked on by a TA tentatively but other contributors welcome.
