PHP elasticsearch部分匹配(PHP elasticsearch partial match)

 我想用elasticsearch搜索并用php显示结果。 我想在前面的mysql中进行部分匹配： 
 
select * from table_name where title like '%abc%'
 
 但我的代码不起作用： 
 
$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        'query' => [
            'match' => [
                'title' => '.*abc.*'
            ]
        ]
    ]
];

i want to search with elasticsearch and show out the result with php. i want to make partial match like it's in mysql for ex: 
 
select * from table_name where title like '%abc%'
 
But my codes doesn`t work:
 
$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        'query' => [
            'match' => [
                'title' => '.*abc.*'
            ]
        ]
    ]
];
