PHP Elasticsearch search on two fields

Question

I want to search in two fields. One field is passed by PHP and the other is entered by the user in the input field.

Can someone help me here?

my code:

        $params = [
        'index' => 'search_documentation',
        'type' => 'document',
        'body' => [
            'size' => 10,
            'query' => [
                'multi_match' => [
                    'match' => [
                        'file.name' => $searchTerm,
                        'relation.machine' => $machineNumber,
                    ],
                ],
            ],
        ],
   ];

Unfortunately, it does not work - it always returns 0 results

---

so the search is fixed but i have now the problem to search correctly. file.name is calling "Anleitung_100_eng.Bedienung.pdf" - if i search for the "keyword" Anleitung or Bedienung they found nothing.. but when i search for example only for "t" then they found that... is this a problem on my query or from the indexing?

$params = [
            'index' => 'search_' . $machineNumber . '_documentation',
            'type' => 'document',
            'size' => 500,
            'body' => [
                'query' => [
                    'prefix' => [
                        'file.name' => $searchTerm,
                        ],
                    ],
            ],
        ];

any ideas?

Answer 1

You need two match queries:

$params = [
    'index' => 'search_documentation',
    'type' => 'document',
    'body' => [
        'size' => 10,
        'query' => [
            'bool' => [
                'must' => [
                  [ 'match' => [
                    'file.name' => $searchTerm
                  ]],
                  [ 'match' => [
                    'relation.machine' => $machineNumber
                  ]]
                ]
            ],
        ],
    ],
];
