Build and execute ElasticSearch queries using a fluent PHP API

Latest Version on Packagist Tests Total Downloads


This package is a lightweight query builder for ElasticSearch. It was specifically built for our elasticsearch-search-string-parser so it covers most use-cases but might lack certain features. We're always open for PRs if you need anything specific!

use Spatie\ElasticsearchQueryBuilder\Aggregations\MaxAggregation;
use Spatie\ElasticsearchQueryBuilder\Builder;
use Spatie\ElasticsearchQueryBuilder\Queries\MatchQuery;

$client = Elastic\Elasticsearch\ClientBuilder::create()->build();

$companies = (new Builder($client))
    ->index('companies')
    ->addQuery(MatchQuery::create('name', 'spatie', fuzziness: 3))
    ->addAggregation(MaxAggregation::create('score'))
    ->search();

Installation

You can install the package via composer:

composer require spatie/elasticsearch-query-builder

Note If you're using elasticsearch/elasticsearch v7 you need to use v1 of this package.

Basic usage

The only class you really need to interact with is the Spatie\ElasticsearchQueryBuilder\Builder class. It requires an \Elastic\Elasticsearch\Client passed in the constructor. Take a look at the ElasticSearch SDK docs to learn more about connecting to your ElasticSearch cluster.

The Builder class contains some methods to add queries, aggregations, sorts, fields and some extras for pagination. You can read more about these methods below. Once you've fully built-up the query you can use $builder->search() to execute the query or $builder->getPayload() to get the raw payload for ElasticSearch.

use Spatie\ElasticsearchQueryBuilder\Queries\RangeQuery;
use Spatie\ElasticsearchQueryBuilder\Builder;

$client = Elastic\Elasticsearch\ClientBuilder::create()->build();

$builder = new Builder($client);

$builder->addQuery(RangeQuery::create('age')->gte(18));

$results = $builder->search(); // raw response from ElasticSearch

Adding queries

The $builder->addQuery() method can be used to add any of the available Query types to the builder. The available query types can be found below or in the src/Queries directory of this repo. Every Query has a static create() method to pass its most important parameters.

The following query types are available:

ExistsQuery

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-exists-query.html

\Spatie\ElasticsearchQueryBuilder\Queries\ExistsQuery::create('terms_and_conditions');

MatchQuery

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-match-query.html

\Spatie\ElasticsearchQueryBuilder\Queries\MatchQuery::create('name', 'john doe', fuzziness: 2, boost: 5.0);

MultiMatchQuery

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-multi-match-query.html

\Spatie\ElasticsearchQueryBuilder\Queries\MultiMatchQuery::create('john', ['email', 'email'], fuzziness: 'auto');

NestedQuery

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-nested-query.html

\Spatie\ElasticsearchQueryBuilder\Queries\NestedQuery::create(
    'user', 
    new \Spatie\ElasticsearchQueryBuilder\Queries\MatchQuery('name', 'john')
);
NestedQuery InnerHits

https://www.elastic.co/guide/en/elasticsearch/reference/current/inner-hits.html

$nestedQuery = \Spatie\ElasticsearchQueryBuilder\Queries\NestedQuery::create(
    'comments',
    \Spatie\ElasticsearchQueryBuilder\Queries\TermsQuery::create('comments.published', true)
);

$nestedQuery->innerHits(
    \Spatie\ElasticsearchQueryBuilder\Queries\NestedQuery\InnerHits::create('top_three_liked_comments')
        ->size(3)
        ->addSort(
            \Spatie\ElasticsearchQueryBuilder\Sorts\Sort::create(
                'comments.likes', 
                \Spatie\ElasticsearchQueryBuilder\Sorts\Sort::DESC
            )
        )
        ->fields(['comments.content', 'comments.author', 'comments.likes'])
);

FunctionScore

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-function-score-query.html

\Spatie\ElasticsearchQueryBuilder\Queries\FunctionScore::create()
    ->addFunction(\Spatie\ElasticsearchQueryBuilder\Queries\FunctionScore\RandomScore::create(123, 'test_field'))
    ->addFunction(\Spatie\ElasticsearchQueryBuilder\Queries\FunctionScore\FieldValueFactor::create('test_field')->factor(2.0))
    ->addFunction(\Spatie\ElasticsearchQueryBuilder\Queries\FunctionScore\Weight::create(2.0));

RangeQuery

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-range-query.html

\Spatie\ElasticsearchQueryBuilder\Queries\RangeQuery::create('age')
    ->gte(18)
    ->lte(1337);

TermQuery

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-term-query.html

\Spatie\ElasticsearchQueryBuilder\Queries\TermQuery::create('user.id', 'flx');

TermsQuery

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-terms-query.html

\Spatie\ElasticsearchQueryBuilder\Queries\TermsQuery::create('user.id', ['flx', 'fly']);

WildcardQuery

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-wildcard-query.html

\Spatie\ElasticsearchQueryBuilder\Queries\WildcardQuery::create('user.id', '*doe');

BoolQuery

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html

\Spatie\ElasticsearchQueryBuilder\Queries\BoolQuery::create()
    ->add($matchQuery, 'must_not')
    ->add($existsQuery, 'must_not');

Chaining multiple queries

Multiple addQuery() calls can be chained on one Builder. Under the hood they'll be added to a BoolQuery with occurrence type must. By passing a second argument to the addQuery() method you can select a different occurrence type:

$builder
    ->addQuery(
        MatchQuery::create('name', 'billie'), 
        'must_not' // available types: must, must_not, should, filter
    )
    ->addQuery(
        MatchQuery::create('team', 'eillish')
    );

More information on the boolean query and its occurrence types can be found in the ElasticSearch docs.

Adding aggregations

The $builder->addAggregation() method can be used to add any of the available Aggregations to the builder. The available aggregation types can be found below or in the src/Aggregations directory of this repo. Every Aggregation has a static create() method to pass its most important parameters and sometimes some extra methods.

use Spatie\ElasticsearchQueryBuilder\Aggregations\TermsAggregation;
use Spatie\ElasticsearchQueryBuilder\Builder;

$results = (new Builder(Elastic\Elasticsearch\ClientBuilder::create()->build()))
    ->addAggregation(TermsAggregation::create('genres', 'genre'))
    ->search();

$genres = $results['aggregations']['genres']['buckets'];

The following query types are available:

CardinalityAggregation

\Spatie\ElasticsearchQueryBuilder\Aggregations\CardinalityAggregation::create('team_agg', 'team_name');

FilterAggregation

https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-filter-aggregation.html

\Spatie\ElasticsearchQueryBuilder\Aggregations\FilterAggregation::create(
    'tshirts',
    \Spatie\ElasticsearchQueryBuilder\Queries\TermQuery::create('type', 'tshirt'),
    \Spatie\ElasticsearchQueryBuilder\Aggregations\MaxAggregation::create('max_price', 'price')
);

MaxAggregation

https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics-max-aggregation.html

\Spatie\ElasticsearchQueryBuilder\Aggregations\MaxAggregation::create('max_price', 'price');

MinAggregation

    'resellers',
    'resellers',
    \Spatie\ElasticsearchQueryBuilder\Aggregations\MinAggregation::create('min_price', 'resellers.price'),
    \Spatie\ElasticsearchQueryBuilder\Aggregations\MaxAggregation::create('max_price', 'resellers.price'),
);

\Spatie\ElasticsearchQueryBuilder\Aggregations\TermsAggregation::create(
    'genres',
    'genre'
)
    ->size(10)
    ->order(['_count' => 'asc'])
    ->missing('N/A')
    ->aggregation(/* $subAggregation */);

\Spatie\ElasticsearchQueryBuilder\Aggregations\TopHitsAggregation::create(
    'top_sales_hits',
    size: 10,
);

Adding sorts

The Builder (and some aggregations) has a addSort() method that takes a Sort instance to sort the results. You can read more about how sorting works in the ElasticSearch docs.

use Spatie\ElasticsearchQueryBuilder\Sorts\Sort;

$builder
    ->addSort(Sort::create('age', Sort::DESC))
    ->addSort(
        Sort::create('score', Sort::ASC)
            ->unmappedType('long')
            ->missing(0)
    );

Nested sort

https://www.elastic.co/guide/en/elasticsearch/reference/current/sort-search-results.html#_nested_sorting_examples

use Spatie\ElasticsearchQueryBuilder\Sorts\NestedSort;

$builder
    ->addSort(
        NestedSort::create('books', 'books.rating', NestedSort::ASC)
    );

Nested sort with filter

use Spatie\ElasticsearchQueryBuilder\Sorts\NestedSort;
use Spatie\ElasticsearchQueryBuilder\Queries\BoolQuery;
use Spatie\ElasticsearchQueryBuilder\Queries\TermQuery;

$builder
    ->addSort(
        NestedSort::create(
            'books', 
            'books.rating', 
            NestedSort::ASC
        )->filter(BoolQuery::create()->add(TermQuery::create('books.category', 'comedy'))
    );

Retrieve specific fields

The fields() method can be used to request specific fields from the resulting documents without returning the entire _source entry. You can read more about the specifics of the fields parameter in the ElasticSearch docs.

$builder->fields('user.id', 'http.*.status');

Highlighting

The highlight() method can be used to add a highlight section to your query along the rules in the ElasticSearch docs.

$highlightSettings = [
    'pre_tags' => ['<em>'],
    'post_tags' => ['</em>'],
    'fields' => [
        '*' => (object) []
    ]
];

$builder->highlight($highlightSettings);

Post filter

The addPostFilterQuery() method can be used to add a post_filter BoolQuery to your query along the rules in the ElasticSearch docs.

use Spatie\ElasticsearchQueryBuilder\Queries\TermsQuery;

$builder->addPostFilterQuery(TermsQuery::create('user.id', ['flx', 'fly']));

Pagination

Finally the Builder also features a size() and from() method for the corresponding ElasticSearch search parameters. These can be used to build a paginated search. Take a look the following example to get a rough idea:

use Spatie\ElasticsearchQueryBuilder\Builder;

$pageSize = 100;
$pageNumber = $_GET['page'] ?? 1;

$pageResults = (new Builder(Elastic\Elasticsearch\ClientBuilder::create()))
    ->size($pageSize)
    ->from(($pageNumber - 1) * $pageSize)
    ->search();
