Introduction

This is a simple package that is used to integrate the Elasticsearch API with a Laravel project.

The package is still in development.

• Client class reference

Installation

Install using composer

  composer require olekjs/elasticsearch

Set Elasticsearch base URL in .env file

ELASTICSEARCH_URL=http://localhost:9200

Custom Indices

Custom Indices work similarly to Laravel models. First, you need to define your own class that extends AbstractIndex:

<?php

namespace App\Indices;

use Olekjs\Elasticsearch\Contracts\AbstractIndex;

class LogIndex extends AbstractIndex
{
    protected string $index = 'logs';
}

You can then use Custom Index to perform a search operation without specifying an index name:

use App\Indices\LogIndex;

...

LogIndex::query()->where('type', 'error')->get();

General usage

There are three options for making requests:

1. Using builder

use Olekjs\Elasticsearch\Builder\Builder;

...

$results = Builder::query()
    ->index('shops')
    ->where('slug', 'test-slug')
    ->where('email', '[email protected]')
    ->whereLike('name', 'test')
    ->whereIn('_id', [123, 321])
    ->get(); // Resturns SearchResponseDto

2. Using Custom Index How to use Custom Indices? See: Custom Indices

use App\Indices\MyCustomIndex;

...

$results = MyCustomIndex::query()
    ->where('slug', 'test-slug')
    ->where('email', '[email protected]')
    ->whereLike('name', 'test')
    ->whereIn('_id', [123, 321])
    ->get(); // Resturns SearchResponseDto

3. Directly using the Client class

use Olekjs\Elasticsearch\Client;

...

$client = new Client();
$client->search('logs', [
  'query' => [
    'bool' => ['filter' => ['term' => ['email' => '[email protected]']]]
  ]
]);

Examples

1. Index the new document

use Olekjs\Elasticsearch\Client;

...

$client = new Client();
$client->create(
  index: 'logs',
  id: 1,
  data: ['level' => 'error', 'message' => 'Error...', ...]
);

2. Find the document

use Olekjs\Elasticsearch\Client;

...

$client = new Client();

// If document doesn't exists null will be returned
$client->find(
  index: 'logs',
  id: 1
);

// If document doesn't exists NotFoundResponseException will be thrown
$client->findOrFail(
  index: 'logs',
  id: 2
);

Client class reference

    public function search(string $index, array $data): SearchResponseDto;

    public function find(string $index, string|int $id): ?FindResponseDto;

    public function findOrFail(string $index, string|int $id): FindResponseDto;

    public function create(string $index, string|int $id, array $data): IndexResponseDto;

    public function update(string $index, string|int $id, array $data): IndexResponseDto;

    public function delete(string $index, string|int $id): IndexResponseDto;

    public function searchWhereIn(string $index, string $field, array $values): SearchResponseDto;

    public function searchWhereKeyword(string $index, string $field, string $value): SearchResponseDto;

    public function searchWhereLike(string $index, string $field, string|int|float $value): SearchResponseDto;

    public function increment(string $index, string|int $id, string $field, int $value = 1): IndexResponseDto;

    public function decrement(string $index, string|int $id, string $field, int $value = 1): IndexResponseDto;

Running Tests

To run tests, run the following command

  php vendor/bin/testbench package:test
