search_query_submission_using_play_framwork.md

This is an example of using Play framework to implement the GET method for submitting search queries.

The URL http://localhost:9000/search will give you the search box. Upon on clicking the search button, the browser will append ?q=<whatever search query that was entered> to the URL and refreshes the page.

The new URL after submission will be http://localhost:9000/search?q=<whatever search query that was entered> and play framwork renders the result page as defined in the controller.

# conf/routes
# Routes file
# Accepts an optional query parameter "q"
GET     /search                     controllers.HomeController.search(q: java.util.Optional[String])

// HomeController.java

public Result search(Optional<String> query) {
    if (query.isPresent()) {
        // renders the page with search results if a query is provided
        return ok("searching for " + query.get());
    }
    
    // renders the normal search box when no query is provided
    return ok(views.html.search.render());
