The text discusses implementing a typeahead search functionality in an application using Golang as the backend language, Couchbase as the NoSQL database, and jQuery for the frontend. The process involves creating a full-text search index, developing a RESTful API to execute queries, and designing a jQuery frontend that utilizes typeahead.js to implement the autocomplete feature. The example uses a simple dataset of song information and demonstrates how to create a native Go data structure to hold search results, configure cross-origin resource sharing for CORS, and render the typeahead functionality using Handlebars templates.
