        // You MUST change it to your server
        $.ajax({
            url: 'http://localhost/kejar/code/search_server.php?q=' + search_value,
            success: function(data){

                // Display the results
                $('#search_results_loader').html('');
                $('#search_results_pos').html(data);
                $('#search_results_neg').html(data);
            }
        })
    })
});

Can you explain where my false?.

Any help will be appreciated. Thanks :)

First of all Don't use GLOBAL

Remove the global sentence from both the scripts and use below code and also check whether this variable is not used in other scripts.

index.php

<?php
//global $pilihdomain;
$pilihdomain=$_POST['cmake'];

search_server.php

<?php 
require 'index.php';
//global $pilihdomain;
...
$resp = $uclassify->classify($tweet['text'],$pilihdomain, 'herlambangp');

Edit

Here you are only sending GET variable q

url: 'http://localhost/kejar/code/search_server.php?q=' + search_value

And because of that $_POST['cmake'] is not available.

First, get rid of all those global $pilihdomain; statements.

Second, $_POST['cmake'] is not populated when you perform a GET request here:

$.ajax({
     url: 'http://localhost/kejar/code/search_server.php?q=' + search_value,
     ...
});

In fact, only $_GET['q'] would be populated.
