I finished with favorites. Can you please help with 2 lines on search?

What is wrong here? Should I use @RequestMapping ?

@RequestMapping("/search?q={keyword}")
public String searchDetails(@RequestParam String keyword, ModelMap modelMap) {

Your @RequestMapping annotation should just have the "vanilla" URI so to speak as a value. No need for q equals something, and yeah, I was initially trying something similar :).

The thing is, the q request parameter is going to be automatically picked up by the Spring framework, since it's a request parameter and is passed in the usual way in the HTTP request. The important thing is that the parameter name is q, and that's about it. The name q is defined in the input tag in the search form and that's all we need to match in our controller method.

So, mine looks like this:

    @RequestMapping("/search")
    public String searchResults(@RequestParam("q") String searchTerm, ModelMap modelMap) {
        List<Gif> gifsFound = gifRepository.searchByName(searchTerm);
        modelMap.put("gifs", gifsFound);

        return "home";
    }

The action in my search form tag is simply "/search" as well.
