Error when performing a 'Search'

[ready2drum]

I recently had moved files from one server to another and now when I'm performing a 'Search' on a web page, the following error message appears:

--------------

Notice: Undefined index: query in E:\Inetpub\wwwroot\Intranet_Old\intranet\jha\jha_doc_results.php on line 62

 

Fatal error: Uncaught exception 'com_exception' with message 'Parameter 0: Type mismatch. ' in E:\Inetpub\wwwroot\Intranet_Old\intranet\jha\jha_doc_results.php:62 Stack trace: #0 E:\Inetpub\wwwroot\Intranet_Old\intranet\jha\jha_doc_results.php(62): unknown() #1 {main} thrown in E:\Inetpub\wwwroot\Intranet_Old\intranet\jha\jha_doc_results.php on line 62

Below is the code showing 'line 62'...

<?php

LIne 59 $Q = new COM("ixsso.Query");

Line 60 $util = new COM("ixsso.util");

Line 61 $Q->Catalog = "E:\GROUP\BIWeb\jha";

Line 62             $Q->Query = $_POST['query'];

$Q->Columns = "filename, rank, vpath, path, DocTitle, characterization, All";

$Q->SortBy = "rank[d]";

$Q->MaxRecords = 200;

$fileRS = $Q->CreateRecordSet("nonsequential");

if(!$fileRS->RecordCount == 0) {

$fileRS->MoveFirst();

}

while($i < $fileRS->RecordCount) {

?>
