Using suggesters


A long time ago, starting from Elasticsearch 0.90 (which was released on April 29, 2013), we got the ability to use so-called suggesters. We can define a suggester as a functionality allowing us to correct the user's spelling mistakes and build autocomplete functionality keeping performance in mind. This section is dedicated to these functionalities and will help you learn about them. We will discuss each available suggester type and show the most common properties that allow us to control them. However, keep in mind that this section is not a comprehensive guide describing each and every property. Description of all the details about suggesters are a very broad topic and is out of the scope of this book. If you want to dig into their functionality, refer to the official Elasticsearch documentation (https://www.elastic.co/guide/en/elasticsearch/reference/current/search-suggesters.html) or to the Mastering Elasticsearch Second Edition book published by Packt Publishing.
