【问题描述】：

这是我在 symfony2 中的查询。我想在此处添加“match_phrase”，但无论我在哪里添加，都会出错。

$params = [
    'index' => 'articles_v2',
    'type' => 'article',
    'body' => [
        "sort"  => [
            [ "date"  =>
                ["order" => "desc"]
            ],
        ],
        "from" => $fromId,
        "size"  => $newsPerPage,
        "query" => [
            "constant_score" => [
                "filter" => [
                    "bool" => [
                        "must" => [
                            ["terms" => [ "article.topics" => $topics ] ],
                            ["match_phrase" => ["article.bodytext" => [$search_phrase] ]]
                        ]
                    ]
                ]
            ]

        ]
    ]
];
$response = $client->search($params);

当我尝试运行此程序时，出现错误： 嵌套：QueryParsingException[[articles_v2] 没有为 [match_phrase]] 注册过滤器； }]","状态":400

那么这个 match_phrase 应该放在哪里呢？（我想得到类似 SQL LIKE '%xxxx%' 的结果）

我已更改查询。这次没有错误，但无论如何，没有过滤。

$params = [
    'index' => 'articles_v2',
    'type' => 'article',
    'body' => [
        "sort"  => [
            [ "date"  =>
                ["order" => "desc"]
            ],
        ],
        "from" => $fromId,
        "size"  => $newsPerPage,
        "query" => [
            "constant_score" => [
                "filter" => [
                    "bool" => [
                        "must" => [
                            ["terms" => [ "article.topics" => $topics ] ]
                        ]
                    ]
                ],
                "query" => [
                    "multi_match" => [
                        "query" =>    $search_phrase, 
                        "fields" => [ "title", "bodytext" ]
                    ]
                ]
            ]
        ]
    ]
];
$response = $client->search($params);

【解决方案1】：

解决方法是不要使用匹配的分数。

您必须使用 query/bool/must 并且所有这些 match 和内部的其他条件 must。

这里是代码。

$params = [
    'index' => 'articles_v2',
    'type' => 'article',
    'size' => 50,
    'body' => [
        "sort"  => [
            [ "date"  =>
                ["order" => "desc"]
            ],
        ],
        "from" => $fromId,
        "size"  => $newsPerPage,
        "query" => [
            "bool" => [
                "must" => [
                    [
                        "match_phrase_prefix" => [
                            "_all" => [
                                "query" => $search_phrase,
                                "operator" => "and",
                                "analyzer" => "analyzer_cs"
                            ]
                        ]
                    ],
                    ["terms" => [ "article.topics" => $topics ] ],
                    ["range" => [ "article.date" => [ "from" => $date_from,"to" => $date_till]]]
                ]
            ]
        ]
    ]
];
