Compatibility
The current version of Elastic Adapter has been tested with the following configuration:
- PHP 8.2
- Elasticsearch 8.x
- Laravel 11.x
If your project uses older Laravel (or PHP) version check the previous major version of the package.
Installation
The library can be installed via Composer:
composer require babenkoivan/elastic-adapter
Configuration
Elastic Adapter uses babenkoivan/elastic-client as a dependency. To change the client settings you need to publish the configuration file first:
php artisan vendor:publish --provider="Elastic\Client\ServiceProvider"
In the newly created config/elastic.client.php
file you can define the default connection name and describe multiple
connections using configuration hashes. Please, refer to
the elastic-client documentation for more details.
Index Management
\Elastic\Adapter\Indices\IndexManager
is used to manipulate indices.
Create
Create an index, either with the default settings and mapping:
$index = new \Elastic\Adapter\Indices\Index('my_index'); $indexManager->create($index);
or configured according to your needs:
$mapping = (new \Elastic\Adapter\Indices\Mapping()) ->text('title', [ 'boost' => 2, ]) ->keyword('tag', [ 'null_value' => 'NULL' ]) ->geoPoint('location') ->dynamic(true) ->dynamicTemplate('no_doc_values', [ 'match_mapping_type' => '*', 'mapping' => [ 'type' => '{dynamic_type}', 'doc_values' => false, ], ]); $settings = (new \Elastic\Adapter\Indices\Settings()) ->index([ 'number_of_replicas' => 2, 'refresh_interval' => -1 ]); $index = new \Elastic\Adapter\Indices\Index('my_index', $mapping, $settings); $indexManager->create($index);
Alternatively, you can create an index using raw input:
$mapping = [ 'properties' => [ 'title' => [ 'type' => 'text' ] ] ]; $settings = [ 'number_of_replicas' => 2 ]; $indexManager->createRaw('my_index', $mapping, $settings);
Drop
Delete an index:
$indexManager->drop('my_index');
Put Mapping
Update an index mapping using builder:
$mapping = (new \Elastic\Adapter\Indices\Mapping()) ->text('title', [ 'boost' => 2, ]) ->keyword('tag', [ 'null_value' => 'NULL' ]) ->geoPoint('location'); $indexManager->putMapping('my_index', $mapping);
or using raw input:
$mapping = [ 'properties' => [ 'title' => [ 'type' => 'text' ] ] ]; $indexManager->putMappingRaw('my_index', $mapping);
Put Settings
Update an index settings using builder:
$settings = (new \Elastic\Adapter\Indices\Settings()) ->analysis([ 'analyzer' => [ 'content' => [ 'type' => 'custom', 'tokenizer' => 'whitespace' ] ] ]); $indexManager->putSettings('my_index', $settings);
or using raw input:
$settings = [ 'number_of_replicas' => 2 ]; $indexManager->putSettingsRaw('my_index', $settings);
Exists
Check if an index exists:
$indexManager->exists('my_index');
Open
Open an index:
$indexManager->open('my_index');
Close
Close an index:
$indexManager->close('my_index');
Put Alias
Create an alias:
$alias = new \Elastic\Adapter\Indices\Alias('my_alias', true, [ 'term' => [ 'user_id' => 12, ], ]); $indexManager->putAlias('my_index', $alias);
The same with raw input:
$settings = [ 'is_write_index' => true, 'filter' => [ 'term' => [ 'user_id' => 12, ], ], ]; $indexManager->putAliasRaw('my_index', 'my_alias', $settings);
Get Aliases
Get index aliases:
$indexManager->getAliases('my_index');
Delete Alias
Delete an alias:
$indexManager->deleteAlias('my_index', 'my_alias');
Connection
Switch Elasticsearch connection:
$indexManager->connection('my_connection');
Document Management
\Elastic\Adapter\Documents\DocumentManager
is used to manage and search documents.
Index
Add a document to the index:
$documents = collect([ new \Elastic\Adapter\Documents\Document('1', ['title' => 'foo']), new \Elastic\Adapter\Documents\Document('2', ['title' => 'bar']), ]); $documentManager->index('my_index', $documents);
There is also an option to refresh index immediately:
$documentManager->index('my_index', $documents, true);
Finally, you can set a custom routing:
$routing = (new \Elastic\Adapter\Documents\Routing()) ->add('1', 'value1') ->add('2', 'value2'); $documentManager->index('my_index', $documents, false, $routing);
Delete
Remove a document from the index:
$documentIds = ['1', '2']; $documentManager->delete('my_index', $documentIds);
If you want the index to be refreshed immediately pass true
as the third argument:
$documentManager->delete('my_index', $documentIds, true);
You can also set a custom routing:
$routing = (new \Elastic\Adapter\Documents\Routing()) ->add('1', 'value1') ->add('2', 'value2'); $documentManager->delete('my_index', $documentIds, false, $routing);
Finally, you can delete documents using query:
$documentManager->deleteByQuery('my_index', ['match_all' => new \stdClass()]);
Search
Search documents in the index:
// configure search parameters $searchParameters = new \Elastic\Adapter\Search\SearchParameters(); // specify indices to search in $searchParameters->indices(['my_index1', 'my_index2']); // define the query $searchParameters->query([ 'match' => [ 'message' => 'test' ] ]); // configure highlighting $searchParameters->highlight([ 'fields' => [ 'message' => [ 'type' => 'plain', 'fragment_size' => 15, 'number_of_fragments' => 3, 'fragmenter' => 'simple' ] ] ]); // add suggestions $searchParameters->suggest([ 'message_suggest' => [ 'text' => 'test', 'term' => [ 'field' => 'message' ] ] ]); // enable source filtering $searchParameters->source(['message', 'post_date']); // collapse fields $searchParameters->collapse([ 'field' => 'user' ]); // aggregate data $searchParameters->aggregations([ 'max_likes' => [ 'max' => [ 'field' => 'likes' ] ] ]); // sort documents $searchParameters->sort([ ['post_date' => ['order' => 'asc']], '_score' ]); // rescore documents $searchParameters->rescore([ 'window_size' => 50, 'query' => [ 'rescore_query' => [ 'match_phrase' => [ 'message' => [ 'query' => 'the quick brown', 'slop' => 2, ], ], ], 'query_weight' => 0.7, 'rescore_query_weight' => 1.2, ] ]); // add a post filter $searchParameters->postFilter([ 'term' => [ 'cover' => 'hard' ] ]); // track total hits $searchParameters->trackTotalHits(true); // track scores $searchParameters->trackScores(true); // script fields $searchParameters->scriptFields([ 'my_doubled_field' => [ 'script' => [ 'lang' => 'painless', 'source' => 'doc[params.field] * params.multiplier', 'params' => [ 'field' => 'my_field', 'multiplier' => 2, ], ], ], ]); // boost indices $searchParameters->indicesBoost([ ['my-alias' => 1.4], ['my-index' => 1.3], ]); // define the search type $searchParameters->searchType('query_then_fetch'); // set the preference $searchParameters->preference('_local'); // use pagination $searchParameters->from(0)->size(20); // search after $searchParameters->pointInTime([ 'id' => '46ToAwMDaWR5BXV1', 'keep_alive' => '1m', ]); $searchParameters->searchAfter([ '2021-05-20T05:30:04.832Z', 4294967298, ]); // use custom routing $searchParameters->routing(['user1', 'user2']); // enable explanation $searchParameters->explain(true); // set maximum number of documents to collect for each shard $searchParameters->terminateAfter(10); // enable caching $searchParameters->requestCache(true); // perform the search and get the result $searchResult = $documentManager->search($searchParameters); // get the total number of matching documents $total = $searchResult->total(); // get the corresponding hits $hits = $searchResult->hits(); // every hit provides access to the related index name, the score, the document, the highlight and more // in addition, you can get a raw representation of the hit foreach ($hits as $hit) { $indexName = $hit->indexName(); $score = $hit->score(); $document = $hit->document(); $highlight = $hit->highlight(); $innerHits = $hit->innerHits(); $innerHitsTotal = $hit->innerHitsTotal(); $raw = $hit->raw(); // get an explanation $explanation = $searchResult->explanation(); // every explanation includes a value, a description and details // it is also possible to get its raw representation $value = $explanation->value(); $description = $explanation->description(); $details = $explanation->details(); $raw = $explanation->raw(); } // get suggestions $suggestions = $searchResult->suggestions(); // get aggregations $aggregations = $searchResult->aggregations();
Connection

is used to control points in time.
Open

$pointInTimeId = $pointInTimeManager->open('my_index', '1m');
Close

$pointInTimeManager->close($pointInTimeId);
Connection
