I've been trying to figure out how to correctly request data from elasticsearch using a jQuery AJAX call. I either get an parsing error or I'll get every document in the index I'm searching under.

    $(document).ready(function() {

    var timer = null;
    function di_search() {
        var box = $('#s_box').val();

        $.ajax({
            url: 'http://localhost:9200/dis/dis/_search',
            type: 'POST',
            //contentType: 'application/json; charset=UTF-8',
            crossDomain: true,
            dataType: 'json',
            data: {
                query:{match:{_all:$('#s_box').val()}},
                pretty: true,
                fields: '_id'
            },
            success: function(response) {
                var data = response.hits.hits;
                var doc_ids = [];
                var source = null;
                var content = '';

                if (data.length > 0) {
                    for (var i = 0; i < data.length; i++) {
                        source = data[i].fields;
                        doc_ids.push(source._id);
                        content = content + ' ' + source._id + '<br />';
                    }

                    $('#res').removeClass('text-error').addClass('text-success').html(content);
                } else {
                    $('#res').removeClass('text-success').addClass('text-error').html('No results found.');
                }


            }
        });
    }

    $('#s_box').live('keyup', function() {

        if (timer) {
            clearTimeout(timer);
        }
        timer = setTimeout(di_search, 600);

    });
});

Here is my error:

                    $('#res').removeClass('text-success').addClass('text-error').html('No results found.');
                }


            },
            error: function(jqXHR, textStatus, errorThrown) {

• 3 The key difference between your original code and your edited code is that you converted your javascript object to JSON and passed that into the $.ajax()'s "data" property by doing JSON.stringify(data). I believe that was the key to getting this to work. – K Lee Commented Mar 18, 2013 at 20:06

You can have a look here: https://github./dadoonet/devoxxfr_demo/blob/gh-pages/index.html#L512

It could help you to solve your issue.

Instead of writing your AJAX call, I'd suggest you use this tool called Postman. Postman has a simple motto -

Making API development easy

So in case you have trouble writing your ES requests, or maybe you decide not to use jQuery AJAX/XHR, and maybe you'd like to use cURL/Unirest/NSURL and what not, you can just use the Postman request builder to write down your simple Http Request, then you'll find a link called code in the box right below that, and you can generate requests in the language of your choice using that. Including AJAX, yes. So I'd remend you try using that.

Here's the link where you can download Postman from - https://www.getpostman./postman
