pagination of search result is not working - php

Question

Pagination problem in search result
I am trying to paginate the search results, Here is the code that i'm using to look up for the search queries from user's form. I am getting search results paginated, but when i click 2 nd page of results it shows undefined index for those item posted...While gone through tutorials i have seen to use $_GET instead of $_POST ,after doing that chane also no improvement in results
As i am new to this php code, can you guys help or guide me in the right direction?
/////////////test.php//////////////////
mysqli_report(MYSQLI_REPORT_ERROR);
// number of results to show per page
$per_page = 2;
// figure out the total pages in the database
if ($result = $mysqli->query("SELECT * FROM bridegroom where Gender like '%$Name%' and Castest like'%$caste%' and Location like '%$location%' order by AGE"))
{
if ($result->num_rows != 0){
$total_results = $result->num_rows;
// ceil() returns the next highest integer value by rounding up value if necessary
$total_pages = ceil($total_results / $per_page);
if (isset($_GET['page']) && is_numeric($_GET['page']))
{
$show_page = $_GET['page'];
if ($show_page > 0 && $show_page <= $total_pages)
{
$start = ($show_page -1) * $per_page;
$end = $start + $per_page;
}
else
{
$start = 0;
$end = $per_page;
}
}
else
{
$start = 0;
$end = $per_page;
}
// display pagination
echo "<p> <b>View search results:</b> ";
for ($i = 1; $i <= $total_pages; $i++)
{
if (isset($_GET['page']) && $_GET['page'] == $i)
{
echo $i . " ";
}
else
{
echo "<a href='test.php?page=$i'>$i</a> ";
}
}
echo "</p>";
// display data in table
// loop through results of database query, displaying them in the table
for ($i = $start; $i < $end; $i++)
{
// make sure that PHP doesn't try to show results that don't exist
if ($i == $total_results) { break; }
// find specific row
$result->data_seek($i);
$row = $result->fetch_row();
// echo out the contents of each row into a table
echo ("Name:$row[1]<br><span class=\"old\"> Age:$row[4]</span><br><span class=\"sold\">Caste:$row[5]</span><br><span class=\"old\">Location:</span><span class=\"sold\">$row[6]</span><br><br>");
}
// close table>
}
else
{
echo "No results to display!";
}
}
// error with the query
else
