Match Query

edit

Here is a standard curl for a Match query:

curl -XGET 'localhost:9200/my_index/my_type/_search' -d '{
    "query" : {
        "match" : {
            "testField" : "abc"
        }
    }
}'

And here is the same query constructed in the client:

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        'query' => [
            'match' => [
                'testField' => 'abc'
            ]
        ]
    ]
];

$results = $client->search($params);

Notice how the structure and layout of the PHP array is identical to that of the JSON request body. This makes it very simple to convert JSON examples into PHP. A quick method to check your PHP array (for more complex examples) is to encode it back to JSON and check by eye:

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        'query' => [
            'match' => [
                'testField' => 'abc'
            ]
        ]
    ]
];

print_r(json_encode($params['body']));


{"query":{"match":{"testField":"abc"}}}

Search results follow the same format as Elasticsearch search response, the only difference is that the JSON response is serialized back into PHP arrays. Working with the search results is as simple as iterating over the array values:

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        'query' => [
            'match' => [
                'testField' => 'abc'
            ]
        ]
    ]
];

$results = $client->search($params);

$milliseconds = $results['took'];
$maxScore     = $results['hits']['max_score'];

$score = $results['hits']['hits'][0]['_score'];
$doc   = $results['hits']['hits'][0]['_source'];
