php - PHP的Elasticsearch结果中缺少突出显示的字段

我正在尝试使用Elasticsearch + Laravel向我的网站添加搜索功能

我使用的软件包可以在这里找到:
https://github.com/cviebrock/laravel-elasticsearch

到目前为止，除了突出显示之外，我都能使所有功能正常运行。这是我的PHP代码:

            $params = [
            'index' => 'my_index',
            'type' => 'web_page',
            'body' => [
                'query' => [
                    'bool' => [
                        'must' => [
                            [
                                'match' => [ 'combined' => $keywords ]
                            ],
                            [
                                'match' => [ 'status' => 1 ],
                            ]
                        ]
                    ]
                ],
                'highlight' => [
                    'pre_tags'  => '<em>',
                    'post_tags' => '</em>',
                    'fields'    => [
                       'combined' => new \stdClass()
                    ]
                ],
            ]
        ];

        try {
            $results = Elasticsearch::search($params);
        } catch (Exception $e) {
            var_dump($e->getMessage());
        }

        dd($results);

我得到的结果如下所示:

array:4 [▼
  "took" => 250
  "timed_out" => false
  "_shards" => array:3 [▶]
  "hits" => array:3 [▼
  "total" => 2
  "max_score" => 0.8117509
  "hits" => array:2 [▼
      0 => array:5 [▶]
      1 => array:5 [▼
        "_index" => "my_index"
        "_type" => "web_page"
        "_id" => "wp_2"
        "_score" => 0.4709723
        "_source" => array:7 [▶]
      ]
    ]
  ]
]

如您所见，我缺少“突出显示”字段，该字段应该在“_source”之后。

我确实遵循了以下页面中描述的说明:

https://www.elastic.co/guide/en/elasticsearch/client/php-api/current/_dealing_with_json_arrays_and_objects_in_php.html

在这里检查了几个相关的问题，但仍然无法弄清楚我做错了什么。

最佳答案

这是我案例中缺少突出显示的解决方案

关于将store => true添加到映射的所有答案都无济于事，包括重新启动elasticsearch等。最后，我正确运行了高亮显示，而根本没有添加它。

flex 搜寻2.3.5
flex PHP库2.x

就我而言，这是['body']['query']['match']['_all']和突出显示特定字段之间的冲突

$params['body']['highlight']['fields']['headline'] = (object) [];
$params['body']['highlight']['fields']['description'] = (object) [];

添加后开始工作

$params['body']['highlight']["require_field_match"] = false;

共享代码段。

$params = [];
$params['index'] = $this->index;
$params['type'] = $this->type;

$perPage = 20;
$offset = $perPage * ($page - 1);

$params['size'] = $perPage;
$params['from'] = $offset;

$params['body']['query']['match']['_all'] = [
    'query' => $searchQuery->getValue(),
    'fuzziness' => 'AUTO'
];

$params['body']['filter']['bool']['must'] = [];
$params['body']['filter']['bool']['must'][] = [
    'term' => ['verified' => true]
];

$params['body']['highlight']['fields']['headline'] = (object) [];
$params['body']['highlight']['fields']['description'] = (object) [];
$params['body']['highlight']["require_field_match"] = false;

$response = $this->elasticClient->search($params);

我希望这可以帮助某人
