Search lite—a query-string search—is useful for ad
hoc queries from the command line.
To harness the full power of search,

Request body search—henceforth known as search—not only handles the query itself, but also allows you to return highlighted snippets from your results, aggregate analytics across all results or subsets of results, and return did-you-mean suggestions, which will help guide your users to the best results quickly.
