php - 如何在Elasticsearch中编写全局查询？

Question

我想使用elasticsearch创建热门搜索查询。

我想从elasticsearch表中匹配category_name，brand_name和title。匹配项应为词组以及with或condition。

我的查询:

$query = [
  "bool" => [
    "must" => [
      ["match" => ["is_published" => 1]],
      [
        "multi_match" => [
          "query" => $searchKey,
          "fields" => ["category_name", "brand_name", "title"]
        ]
      ],
      [
        'nested' => [
          'path' => 'category_with_in_title.parent_cat',
          'query' => [
            'bool' => [
              'must' => [

                ['match' => [
                  'category_with_in_title.parent_cat.status' => 1,
                ]],
              ],
            ],
          ],
        ],
      ],
      [
        'nested' => [
          'path' => 'brand',
          'query' => [
            'bool' => [
              'must' => [
                'match' => [
                  'brand.approved_status' => 1,
                ],
              ],
            ],
          ],
        ],
      ],
      [
        'nested' => [
          'path' => 'default_product_low_price_with_seller.seller_detail',
          'query' => [
            'bool' => [
              'must' => [
                'match' => [
                  'default_product_low_price_with_seller.seller_detail.approve_status' => 1,
                ],
              ],
            ],
          ],
        ],

      ],
      [
        'nested' => [
          'path' => 'default_product_low_price_with_seller',
          'query' => [
            'bool' => [
              'must' => [
                'match' => [
                  'default_product_low_price_with_seller.status' => 1,
                ],
              ],
            ],
          ],
        ],
      ],
    ],

  ],
];

我为此使用 multi_match，但如何在此查询中使用pharse？我必须写整个词来搜索。

例如 :

我要搜索其 category_name = Tops的记录

如果我写“tops”或“top”或“to”，我想要结果。但是现在我必须写“Tops”一词。

您可以使用match_phrase_prefix，它与match_phrase相同，不同之处在于允许在文本的最后一项上进行前缀匹配。

您需要做的就是将"type": "phrase_prefix"添加到multi_match查询中，如下所示:

"multi_match" => [
  "query" => $searchKey,
  "type": "phrase_prefix",
  "fields" => ["category_name", "brand_name", "title"]
]

让我知道这是否是您想要的。
