Hi Alessandro,
Can you use a javascript library which handles ajax and json / jsonp
You will end up with much cleaner client code for example a jquery
implementation looks quite nice using solrs neat jsonp support:
queryString = "*:*"
$.getJSON(
"http://[server]:[port]/solr/select/?jsoncallback=?";,
{"q": queryString,
"version": "2.2",
"start": "0",
"rows": "10",
"indent": "on",
"json.wrf": "callbackFunctionToDoSomethingWithOurData",
"wt": "json",
"fl": "field1"}
);
and the callback function
function callbackFunctionToDoSomethingWithOurData(solrData) {
// do stuff with your nice data
}
Their is also a javascript client for solr as well but i've not used this
Cheers Lee C
