Building a search page isn’t as straight forward as you’d think. At first, a client will want something which users can search content, then they may want to modify the search results or even change the ranking of certain content. Long story short, something you thought would be as simple as enabling a module, ends up taking twice as long.

Drupal 8 core Search has been revamped and is much more powerful and accurate than in D7, but it still concentrates on the text in nodes and not other entities those nodes might contain—like Paragraphs, Views, or custom blocks. Core Search also does not allow you to choose which fields you want to index, how important those fields are, or use any preprocessors to tailor your search. Search API gives you all this and more.

However, if you wish to install a more powerful search engine on your website, then follow the steps below.
