@RestController
public class GoogleSearchController {

    @GetMapping("/search")
    public String searchGoogle(@RequestParam String query) throws Exception {
        CloseableHttpClient httpClient = HttpClients.createDefault();
        HttpGet request = new HttpGet("https://www.google.com/search?q=" + query);
        try (CloseableHttpResponse response = httpClient.execute(request)) {
            HttpEntity entity = response.getEntity();
            if (entity != null) {
                return EntityUtils.toString(entity);
            }
        }
        return "No results found";
    }
}
