Php 仅突出显示查询

我正在使用php中的elasticsearch，并尝试使用如下突出显示我的参数：

$params = [
     'index' => 'idx',
        'type' => 'type',
        'body' => [
            'query' => [
                'bool' => [
                    'should' => [
                           ['wildcard' => [
                            "identifier.contact.firstName" => '*' . $search . '*'
                        ]]
                     ]
                ]
            ],
            'sort' => [
                "id" => ["order" => "desc"]

            ],
            'highlight' => [
                'fields' => [
                    "identifier.contact.firstName" => new \stdClass()
                ],
            ]
        ],

因此，除了在我的

突出显示

字段中，它工作得非常好

或

但一切都没有改变。我还尝试了片段大小和片段数量的几个值。我设法用一种改变高光的算法来处理这个问题，但我发现这很糟糕

我的配置：

 'body' => [
                'settings' => [
                    'number_of_shards' => 5,
                    'number_of_replicas' => 0,
                    'analysis' => [
                        'my_analyzer' => [
                            "tokenizer" => "my_tokenizer"
                        ],
                        "tokenizer" => [
                            "my_tokenizer" => [
                                "type"=> "ngram",
                                "min_gram" => 1,
                                "max_gram" => 10,
                                "token_char" => [
                                    "letter",
                                    "digit"
                                ]
                            ]
                        ]
                    ]
                ],

您可以显示索引配置？看起来您可以通过“空格”符号标记短语。我认为使用

ngram

tokenizer对你有帮助。@maximku好的，我阅读了关于ngram的文档并更新了我的配置文件，我添加了它，所以请检查你对它的看法设置

minu ngram

到2，因为在某些版本中，弹性体有bug:）@maximku它工作得很好，谢谢。添加一个答案，这样我就可以验证它，如果你不想，我会的
