Search is an important feature in website documentation, it allows the users to find easily the target content. Engrafia uses the levenshtein distance, and damerau-levenshtein distance, it's a tiny but powerful resource to find contents.

The search is based on the title, description, and tags of a document, so, to provide a better experience to the user, you should add a good title, and good descriptions, followed by correct tags, that is not just about a good Engrafia search, but Google and search engines search too.
