PHP와 Elasticsearch를 사용하여 자동 완성 검색 기능을 구축하는 방법

require 'vendor/autoload.php'; use ElasticsearchClientBuilder; $client = ClientBuilder::create()->build(); $params = [ 'index' => 'products', 'body' => [ 'mappings' => [ 'properties' => [ 'autocomplete' => [ 'type' => 'text', 'analyzer' => 'autocomplete', 'search_analyzer' => 'standard', ] ] ], 'settings' => [ 'analysis' => [ 'analyzer' => [ 'autocomplete' => [ 'type' => 'custom', 'tokenizer' => 'standard', 'filter' => ['lowercase', 'autocomplete_filter'], ], ], 'filter' => [ 'autocomplete_filter' => [ 'type' => 'edge_ngram', 'min_gram' => 1, 'max_gram' => 20, ], ], ], ], ], ]; $response = $client->indices()->create($params);

require 'vendor/autoload.php'; use ElasticsearchClientBuilder; $client = ClientBuilder::create()->build(); $csvFile = fopen('products.csv', 'r'); while (($data = fgetcsv($csvFile, 1000, ',')) !== false) { $params = [ 'index' => 'products', 'body' => [ 'autocomplete' => $data[1], ], ]; $client->index($params); } fclose($csvFile);

require 'vendor/autoload.php'; use ElasticsearchClientBuilder; $client = ClientBuilder::create()->build(); $params = [ 'index' => 'products', 'body' => [ 'query' => [ 'match_phrase_prefix' => [ 'autocomplete' => [ 'query' => $_GET['term'] ] ], ], ], ]; $response = $client->search($params); $suggestions = []; foreach ($response['hits']['hits'] as $hit) { $suggestions[] = $hit['_source']['autocomplete']; } echo json_encode($suggestions);
