使用 Laravel 进行弹性搜索中整数的查询匹配

Question

我按照这篇文章连接 laravel 和 ElasticSearch： https://madewithlove.be/how-to-integrate-your-laravel-app-with-elasticsearch/

我在 MySQL 数据库中有一个表，它具有树字段：“title”、“description”和“price”。 “标题”和“描述”是字符串类型。所以我写了下面的代码进行搜索，这工作正常：

private function searchOnElasticsearch(string $query): array
{
    $instance = new Article;

    $items = $this->search->search([
        'index' => $instance->getSearchIndex(),
        'type' => $instance->getSearchType(),
        'body' => [
            'query' => [
                'multi_match' => [
                    'fields' => ['title', 'description'],
                    'query' => $query,
                ],
            ],
        ],
    ]);

    return $items;
}

但是现在，我需要检查 bigInt 类型 的“价格”字段，就像其他两个字段一样：'fields' => ['title', 'description','price'],

更新

当我在字段中添加“价格”时，我在 laravel 中收到此错误：

{"error":{"root_cause":[{"type":"query_shard_exception","re​​ason":"失败 创建查询： {\n \"multi_match\" : {\n \"query\" : \"bad\",\n \"字段\" : [\n \"描述^1.0\",\n \"价格^1.0\",\n \"tags^1.0\",\n \"title^1.0\"\n ],\n \"type\" : \"best_fields\",\n \"operator\" : \"OR\",\n \"slop\" : 0,\n \"prefix_length\" : 0,\n \"max_expansions\" : 50,\n \"zero_terms_query\" : \"NONE\",\n \"auto_generate_synonyms_phrase_query\" : true,\n \"fuzzy_transpositions\" : true,\n \"boost\" : 1.0\n }\n}","index_uuid":"mm787GxMS4WjjjqwRD5YIw","index":"commodities"}],"type":"search_phase_execution_exception","re​​ason":"all 碎片 失败","阶段":"查询","分组":true,"failed_shards":[{"shard":0,"index":"commodities","node":"JYWiIdbLQtu3aWkm_F-e9Q","re​​ason" :{"type":"query_shard_exception","re​​ason":"失败 创建查询： {\n \"multi_match\" : {\n \"query\" : \"bad\",\n \"字段\" : [\n \"描述^1.0\",\n \"价格^1.0\",\n \"tags^1.0\",\n \"title^1.0\"\n ],\n \"type\" : \"best_fields\",\n \"operator\" : \"OR\",\n \"slop\" : 0,\n \"prefix_length\" : 0,\n \"max_expansions\" : 50,\n \"zero_terms_query\" : \"NONE\",\n \"auto_generate_synonyms_phrase_query\" : true,\n \"fuzzy_transpositions\" : true,\n \"boost\" : 1.0\n }\n}","index_uuid":"mm787GxMS4WjjjqwRD5YIw","index":"commodities","caused_by":{"type":"number_format_exception","re​​ason":"For 输入字符串：\"bad\""}}}]},"status":400}

我建议这样的事情，即将查询分成两部分，一个用于文本字段，另一个用于数字字段。但是，如果 $query 确实是数字，则仅在数字字段上添加匹配项：

$body = [
    'query' => [
        'bool' => [
            'should' => [
                [
                   'multi_match' => [
                       'fields' => ['title', 'description'],
                       'query' => $query
                   ]
                ]
            ]
        ]
    ]
];

// if the query is numeric add an additional clause for the price field
if (is_numeric($query)) {
    $body['query']['bool']['should'][] = [ 'match' => [ 'price' => $query]];
}

$items = $this->search->search([
    'index' => $instance->getSearchIndex(),
    'type' => $instance->getSearchType(),
    'body' => $body
]);
