Once we have the search in place, we need to improve the entire search experience. Improving the search experience means to provide a hassle-free and seamless search and the ability to get results for the user on the first try. In various contexts, this might mean differently. In some situations, considering the synonyms of the search term might help the user better. In other situations, providing a provision to search an e-mail or link in an unstructured text might help the user more. In short, the search engine should be able to guess what the user is searching for even if the user hasn't provided the right term to search.

In this chapter, we will explore various search patterns from a user's perspective and then, we'll go further to understand how these patterns arise. Later on, we will focus on how to solve them with the help of internal and external analyzers and plugins developed for Elasticsearch.
