ElasticSearch多字段搜索语法错误

我在下图的几个字段中看到多个条件:

我试着加入我的Laravel 5.7应用程序(带有ElasticSearch/ElasticSearch插件),如以下代码所示:

$elasticQuery = [
    "bool" => [
        'must'   => [
            'multi_match' => [
                'query'  => $text,
                'fields' => ['name^4', 'description']
            ],
        ],
        "should" => [
            'term' => [
                "category_id" => 1,
            ]
        ]
    ]
];

但我得到了错误:

{"error":{"root_cause":[{"type":"parsing_exception","reason":"[bool] malformed query, expected [END_OBJECT] but found [FIELD_NAME]","line":1,"col":130}],"type":"parsing_exception","reason":"[bool] malformed query, expected [END_OBJECT] but found [FIELD_NAME]","line":1,"col":130},"status":400}

但当我使用一个简单的条件时:

        $elasticQuery = [
            'multi_match' => [
                'query' => $text,
                'fields' => ['name^4', 'description'],
            ],
        ];

我得到了一个有效的结果:

[hits] => Array
    (
        [total] => 1
        [max_score] => 7.4126062
        [hits] => Array
            (
                [0] => Array
                    (
                        [_index] => select_vote
                        [_type] => vote
                        [_id] => 16
                        [_score] => 7.4126062
                        [_source] => Array
                            (
                                [id] => 16
                                [slug] => in-the-film-babe-what-type-of-animal-was-babe
                                [name] => In the film Babe, what type of animal was Babe?
                                [description] => Babe is a 1995 A...
                                [created_at] => 2018-11-10 09:14:15
                                [category_id] => 2
                                [category] => Array
                                    (
                                        [name] => Movie&Cartoons
                                        [slug] => movie-cartoons
                                        [created_at] => 2018-11-10 09:14:12
                                    )

                            )

                    )

            )

    )

这是多请求的有效格式吗?

修改块2: 做一些搜索,我找到了工作:

$elasticQuery = [
    "bool" => [
        'should' => [


                [
                        "multi_match" => [
                            "query"  => $text,
                            "type"   => "cross_fields",
                            "fields" => [
                                "name^4",
                                "description"
                            ]
                        ]
                ],

                [
                    'match' => [
                        'category_id' => [
                            'query' => 1,
                        ]
                    ]
                ],

                [
                    'match' => [
                        'category_id' => [
                            'query' => 3,
                        ]
                    ]
                ],

        ]
    ]
];

当我需要按文本字段和上面示例中的类别(1和3)数组进行搜索时,它可以工作,但看起来像是“或”条件,但我需要进行类似“和”的限制,使用SQL术语…

哪种方式正确,才能做出“和”这样的限制?

谢谢!

$elasticQuery = [ "bool" => [ 'must' => [ [ "multi_match" => [ "query" => $text, "type" => "cross_fields", "fields" => [ "name^4", "description" ] ] ], ], 'filter' => [ [ 'terms' => [ 'category_id' => [ 1, 3 ] ] ] ] ] ];
