saxulum/saxulum-elasticsearch-querybuilder

A query builder for elasticsearch

saxulum-elasticsearch-querybuilder

, _(*1)

Features

• A simple to use, flexible query builder for elastic search.

Requirements

• php: ~7.0

Suggests

• saxulum/saxulum-elasticsearch-querybuilder-generator: ~1.0

Installation

Through Composer as saxulum/saxulum-elasticsearch-querybuilder., _(*2)

composer require saxulum/saxulum-elasticsearch-querybuilder "~3.3"

Usage

Important: By default empty nodes get not serialized. NullNode forces null value serialization., _(*3)

• ArrayNode (no elements)
• BoolNode (null)
• ObjectNode (no elements)
• FloatNode (null)
• IntNode (null)
• StringNode (null)

This works recursive, which means theoretically a complex query builder can lead into an empty string as json query., _(*4)

Check the allowSerializeEmpty argument to prevent this if needed., _(*5)

QueryBuilder

use Saxulum\ElasticSearchQueryBuilder\Node\ObjectNode;
use Saxulum\ElasticSearchQueryBuilder\Node\StringNode;
