The video tutorial explains the concept of ngrams and their application in search systems, particularly in Elasticsearch. It covers the creation of unigrams, bigrams, and trigrams, and introduces edge ngrams for efficient prefix matching. The tutorial also guides on setting up a custom analyzer in Elasticsearch for autocomplete functionality and discusses the use of different analyzers for indexing and querying. Finally, it introduces completion suggestions for enhanced control over autocomplete processes.

How does the choice of analyzer differ between the index side and the query side in Elasticsearch?

What are completion suggestions in Elasticsearch and when would you use them?
