php-elasticaHow can I use the PHP Elastica Key to search for data?

The PHP Elastica Key is a powerful tool for searching data stored in an Elasticsearch index. It allows you to query the index for specific data, and then return the results in a structured format.

To use the PHP Elastica Key, you first need to include the library in your project. You can do this with the following code:

require_once 'vendor/autoload.php';

Once the library is included, you can create an instance of the Elastica Client and use it to create a search query. For example, the following code will search for documents with the term “Elastica” in their title:

$client = new Elastica\Client();
$query = new Elastica\Query();
$termQuery = new Elastica\Query\Term();
$termQuery->setTerm('title', 'Elastica');
$query->setQuery($termQuery);
$results = $client->search($query);

The results of the search query will be returned in a structured format, which you can then use to display the relevant data.

The following list contains parts of the code used in the example above:

• require_once 'vendor/autoload.php';: This includes the Elastica library in your project.
• $client = new Elastica\Client();: This creates an instance of the Elastica Client.
• $query = new Elastica\Query();: This creates a new search query.
• $termQuery = new Elastica\Query\Term();: This creates a term query, which is used to search for specific terms in documents.
• $termQuery->setTerm('title', 'Elastica');: This sets the term to search for in the documents.
• $query->setQuery($termQuery);: This sets the query to use when searching.
• $results = $client->search($query);: This executes the search query and returns the results.
