使用Laravel在弹性搜索中查询整数的匹配项

Question

I followed this article for connecting laravel and ElasticSearch: https://madewithlove.be/how-to-integrate-your-laravel-app-with-elasticsearch/

I have a table in MySQL database that it has tree field:"title","description" and "price". "title" and "description is string type. so I write below code for searching and this worked correctly:

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;
}

But now, I need to check "price" field that is a bigInt type like two other field: 'fields' => ['title', 'description','price'],

UPDATE

When I add "price" to field I get this error in laravel:

{"error":{"root_cause":[{"type":"query_shard_exception","reason":"failed to create query: {\\n \\"multi_match\\" : {\\n \\"query\\" : \\"bad\\",\\n \\"fields\\" : [\\n \\"description^1.0\\",\\n \\"price^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","reason":"all shards failed","phase":"query","grouped":true,"failed_shards":[{"shard":0,"index":"commodities","node":"JYWiIdbLQtu3aWkm_F-e9Q","reason":{"type":"query_shard_exception","reason":"failed to create query: {\\n \\"multi_match\\" : {\\n \\"query\\" : \\"bad\\",\\n \\"fields\\" : [\\n \\"description^1.0\\",\\n \\"price^1.0\\",\\n \\"tags^1.0\\",\\n \\"title^1.0\\"\\n ],\\n \\"type\\" : \\"best_fields\\",\\n \\"oper ator\\" : \\"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","reason":"For input string: \\"bad\\""}}}]},"status":400}

Answer 1

I suggest something like this, ie split the query into two parts, one for text fields and another for numeric fields. However, only add the match on numeric fields if the $query is indeed a number:

$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
]);
