Getting started 🐣

Using this client assumes that you have already an instance of Elastic App Search up and running.

You can find more information about Elastic App Search at : https://www.elastic.co/app-search.

You can install the client in your project by using composer:

composer require elastic/app-search

Versioning

This client is versioned and released alongside App Search.

To guarantee compatibility, use the most recent version of this library within the major version of the corresponding App Search implementation.

For example, for App Search 7.3, use 7.3 of this library or above, but not 8.0.

If you are using the SaaS version available on swiftype.com of App Search, you should use the version 7.5.x of the client.

Usage

Configuring the client

Basic client instantiation

To instantiate a new client you can use \Elastic\AppSearch\Client\ClientBuilder:

  $apiEndpoint   = 'http://localhost:3002/';
  $apiKey        = 'private-XXXXXXXXXXXX';
  $clientBuilder = \Elastic\AppSearch\Client\ClientBuilder::create($apiEndpoint, $apiKey);

  $client = $clientBuilder->build();

Notes:

The resulting client will be of type \Elastic\AppSearch\Client\Client
You can find the API endpoint and your API key URL in the credentials sections of the App Search dashboard.
You can use any type of API Key (private, public or admin). The client will throw an exception if you try to execute an action that is not authorized for the key used.

Basic usage

Retrieve or create an engine

Most methods of the API require that you have access to an Engine.

To check if an Engine exists and retrieve its configuration, you can use the Client::getEngine method :

  $engine = $client->getEngine('my-engine');

If the Engine does not exists yet, you can create it by using the Client::createEngine method :

  $engine = $client->createEngine('my-engine', 'en');

The second parameter ($language) is optional. Set it to null to apply the universal language.

Index some documents

You can use the Client::indexDocuments method to index some documents into the Engine:

    $documents = [
      ['id' => 'first-document', 'name' => 'Document name', 'description' => 'Document description'],
      ['id' => 'other-document', 'name' => 'Other document name', 'description' => 'Other description'],
    ];

    $indexingResults = $client->indexDocuments('my-engine', $documents);

The $indexingResults array will contain the result of the indexation of each documents. You should always check the content of the result.

Search

You can use the Client::search method to search in your Engine:

    $searchParams = [
      'page'  => ['current' => 1, 'size' => 10]
    ];

    $searchResponse = $client->search('my-engine', 'search text', $searchParams);

If you want to match all documents you can use and empty search query '' as second parameter ($queryText).

The $searchRequestParams parameter is optional and can be used to use advanced search features. Allowed params are :

Param name	Documentation URL
`page`	https://swiftype.com/documentation/app-search/api/search#paging
`filters`	https://swiftype.com/documentation/app-search/api/search/filters
`facets`	https://swiftype.com/documentation/app-search/api/search/facets
`sort`	https://swiftype.com/documentation/app-search/api/search/sorting
`boosts`	https://swiftype.com/documentation/app-search/api/search/boosts
`search_fields`	https://swiftype.com/documentation/app-search/api/search/search-fields
`result_fields`	https://swiftype.com/documentation/app-search/api/search/result-fields
`group`	https://swiftype.com/documentation/app-search/api/search/grouping

The search response will contains at least a meta field and a results field as shown in this example:

[
    'meta' => [
      'warnings' => [],
      'page' => [
        'current' => 1,
        'total_pages' => 1,
        'total_results' => 1,
        'size' => 10
      ],
      'request_id' => 'feff7cf2359a6f6da84586969ef0ca89'
    ],
    'results' => [
      [
        'id' => ['raw' => 'first-document'],
        'name' => ['raw' => 'Document name'],
        'description' => ['raw' => ['Document description']
      ]
    ]
  ]
]

Development

Code for the endpoints is generated automatically using a custom version of OpenAPI Generator.

To regenerate endpoints, use the docker laucher packaged in vendor/bin:

./vendor/bin/elastic-openapi-codegen.sh

The custom generator will be built and launched using the following Open API spec file : resources/api/api-spec.yml.

You can then commit and PR the modified api-spec file and your endpoints code files.

The client class and readme may be changed in some cases. Do not forget to include them in your commit!
