I'm attempting to write ajax code in a PHP file that queries elasticsearch  
server and returns a JSON document:

var load\_data = function() {  
$.ajax({ url: '[http://localhost:9200/inventory/\_search?pretty=true](http://localhost:9200/inventory/_search?pretty=true)'  
, type: 'POST'  
, data :  
???????????????????  
"query":{"match\_all":{}}  
})

I'm not sure what I need to type before my query to return a JSON document.  
Could someone lend a hand? 🙂
