我正在尝试使用 PHP 和 AJAX 制作一个 Web 应用程序。它应该从 Elasticsearch 检索数据而不刷新页面（实时搜索）。是否可以在弹性搜索索引上实现这种检索？为此，我制作了这两个文件：index2.php
<?php
session_start();
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<div class="container">

<h2 align="center">Ajax Live Data Search using Jquery, PHP, Elasticsearch</h2><br />
<div class="form-group">
<div class="input-group">
<span class="input-group-addon">Search</span>
<input type="text" name="search_text" id="search_text" placeholder="Search by Customer Details" class="form-control" />
</div>
</div>
<br />
<div id="result"></div>
</div>
</body>
</html>
<script>
$(document).ready(function(){
load_data();
function load_data(query)
{
$.ajax({
url:"fetch2.php",
method:"POST",
data:{query:query},
success:function(data)
{
$('#result').html(data);
}
});
}
$('#search_text').keyup(function(){
var search = $(this).val();
if(search != '')
{
load_data(search);
}
else
{
load_data();
}
});
});
</script>
