Feature 1: Group Similar Titles

Problem Statement

Suppose you are building an app like Netflix and the content library contains the following titles: "duel", "dule", "speed", "spede", "deul", "cars". How would you efficiently implement a functionality so that if a user misspells speed as spede, they are shown the correct title?

We want to split the list of titles into sets of words so that all words in a set are anagrams. In the above list, there are three sets: {"duel", "dule", "deul"}, {"speed", "spede"}, and {"cars"}. Search results should comprise all members of the set that the search string is found in. We should pre-compute these sets instead of forming them when the user searches for a title.
