Question

我关注了这篇文章，以连接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，该表具有树字段：“标题”，“描述”和“价格”。 “标题”和“描述是字符串类型。所以我在下面编写了用于搜索的代码，此代码可以正常工作：

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，我需要像其他两个字段一样检查属于 bigInt类型的“价格”字段：'fields' => ['title', 'description','price'],

更新

当我在字段中添加“价格”时，在laravel中出现此错误：

{“错误”：{“ root_cause”：[{“类型”：“ query_shard_exception”，“原因”：“失败创建查询：{\ n \“ multi_match \”：{\ n \“ query \”：\“坏\”，\ n \“ fields \”：[\ n \“描述^ 1.0 \”，\ n \“价格^ 1.0 \”，\ n \“ tags ^ 1.0 \”，\ n \“ title ^ 1.0 \” \ n]，\ n \“ type \”：\“最佳字段\”，\ 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“：”商品“}]，”类型“：” search_phase_execution_exception“，”原因“：”全部分片失败”，“阶段”：“查询”，“分组”：true，“ failed_shards”：[{“ shard”：0，“ index”：“ commodities”，“ node”：“ JYWiIdbLQtu3aWkm_F-e9Q”，“ reason” ：{“类型”：“ query_shard_exception”，“原因”：“失败创建查询：{\ n \“ multi_match \”：{\ n \“ query \”：\“坏\”，\ n \“ fields \”：[\ n \“描述^ 1.0 \”，\ n \“价格^ 1.0 \”，\ n \“ tags ^ 1.0 \”，\ n \“ title ^ 1.0 \” \ n]，\ n \“ type \”：\“最佳字段\”，\ 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“：”商品“，” caused_by“：{” type“：” number_format_exception“，” reason“：” For 输入字符串：\“ bad \”“}}}]}，”状态“：400}

我建议使用类似的方法，即将查询分为两部分，一部分用于文本字段，另一部分用于数字字段。但是，仅当$query确实是数字时，才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
]);

使用Laravel
