    url: "<?php echo base_url(); ?>index.php/users/search"+CityINP+distINPx+CategoryINP+textINP+latlog,
    type: "POST",
    data: pdata,
    dataType: "JSON",
    success: function (data) {
        // if success reload ajax table
         alert("success");
        // reload_table();
    },
    error: function (jqXHR, textStatus, errorThrown) {
        alert('Error adding / update data');

At first, I will suggest you to make a js variable in header section like this 

<script type="text/javascript">
        var BASE_URL = "<?php echo base_url(); ?>";
</script>

In this way, you won't have to write echo baseurl everytime in the URL.

$.ajax({
    type: 'POST',
    url: BASE_URL + "controllerName/search",
    data: {'CityINP': distINPx,'CategoryINP':latlog },
    success: function (data) {
    data = JSON.parse(data);
    if(data.response == "response")
    {
        //do anything you want from the response you get
    }
 }
});

To get the parameters in the controller function you can get it by the following code

$this->input->post('CityINP');
$this->input->post('CategoryINP');

change your url url: "index.php/users/search"+CityINP+distINPx+CategoryINP+textINP+latlog,

to url: "index.php/users/search/"+CityINP+distINPx+CategoryINP+textINP+latlog,

"/" after search function name, in your url all variables are concat with search funaction name.
