PHP elasticsearch 部分匹配

Question

我想用elasticsearch搜索并用php显示结果。我想像 mysql 中那样进行部分匹配，例如:

select * from table_name where title like '%abc%'

但是我的代码不起作用:

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        'query' => [
            'match' => [
                'title' => '.*abc.*'
            ]
        ]
    ]
];

Answer 1

我使用“match”而不是“regex”

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        'query' => [
            'regexp' => [
                'title' => '.*abc.*'
            ]
        ]
    ]
];
