Informations about the package elasticsearch-query-builder
Build and execute ElasticSearch queries using a fluent PHP API
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!

Installation
You can install the package via composer:
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 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.
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
MatchQuery
https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-match-query.html
MultiMatchQuery
https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-multi-match-query.html
NestedQuery
https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-nested-query.html
RangeQuery
https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-range-query.html
TermQuery
https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-term-query.html
WildcardQuery
[https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-wildcard-query.html](https://www. elastic.co/guide/en/elasticsearch/reference/current/query-dsl-wildcard-query.html)
BoolQuery
https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html
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:
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 Aggregation
s 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.
The following query types are available:
CardinalityAggregation
FilterAggregation
https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-filter-aggregation.html
MaxAggregation
https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics-max-aggregation.html
MinAggregation
https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics-min-aggregation.html
NestedAggregation
https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-nested-aggregation.html
ReverseNestedAggregation
https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-reverse-nested-aggregation.html
TermsAggregation
https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html
TopHitsAggregation
https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics-top-hits-aggregation.html
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.
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.
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:
