aws-elasticsearch-laravel

AWS Elasticsearch Service for Laravel/Lumen

NOTE: This package only caters search, aggregation, and indexing transactions. Other than that, you can refer to elasticsearch's official documentation.

Installation

composer require elegisandi/aws-elasticsearch-laravel

Laravel/Lumen Integration

• Add service provider to your config/app.php providers

  elegisandi\AWSElasticsearchService\ElasticSearchServiceProvider::class
  

• Add facade to your config/app.php aliases

  'ElasticSearch' => elegisandi\AWSElasticsearchService\Facades\ElasticSearch::class
  

• Set AWS credentials and Elasticsearch config in your .env file

    AWS_ACCESS_KEY_ID
    AWS_SECRET_ACCESS_KEY
    AWS_REGION
  
    ELASTICSEARCH_ENDPOINT
    ELASTICSEARCH_PORT
    ELASTICSEARCH_SHARDS
    ELASTICSEARCH_REPLICAS
    ELASTICSEARCH_DEFAULT_INDEX
    ELASTICSEARCH_DEFAULT_TYPE
    ELASTICSEARCH_DEFAULT_TIME_FILTER_FIELD
  

  When you are already using aws elasticsearch service, set

    AWS_ELASTICSEARCH_SERVICE=true
  

If you want to configure elasticsearch mappings, settings and/or default type and index, just run:

php artisan vendor:publish --provider=elegisandi\\AWSElasticsearchService\\ElasticSearchServiceProvider

For Lumen:

• Register service provider to your bootstrap/app.php

  $app->register(elegisandi\AWSElasticsearchService\ElasticSearchServiceProvider::class);      
  

Basic Usage

Using Facade:

<?php
    
namespace App;

use ElasticSearch;

public function index() {
    extract(ElasticSearch::setSearchParams(request()));

    $clicks = [];
    $total = 0;

    if ($hits = ElasticSearch::search($query, $options, $date_range)) {
        $clicks = $hits['hits']['hits'];
        $total = $hits['hits']['total'];
    }
}

For Lumen:

<?php
        
namespace App;

public function index() {
    extract(app('elasticsearch')->setSearchParams(request()));

    $clicks = [];
    $total = 0;

    if ($hits = app('elasticsearch')->search($query, $options, $date_range)) {
        $clicks = $hits['hits']['hits'];
        $total = $hits['hits']['total'];
    }
}

Console Commands

• Create Index (creates the default index)

  php artisan elasticsearch:create-index

  To reset existing index,

  php artisan elasticsearch:create-index --reset

• Update Index Mapping (updates the default index mapping)

  php artisan elasticsearch:update-index-mapping

  Only supports new properties updates.

Available Methods

• aggregations(array $aggs, array $query = [], array $options = [], $type, $index)

  $aggs : must follow the structure specified in elasticsearch docs.

  $query : see search method $query argument

  $options : see search method $options argument

  returns Array

• search(array $query = [], array $options = [], array $range = [], $type, $index)

  $query : an array of key-value pair of any available properties

  $options : an array of key-value pair of the ff: from, size, sort

  $range : an array representation of range query.

  returns Array

• count(array $query = [], array $range = [], $type, $index)

  a (syntactic sugar) method of search with zero hits result

  returns Int

• setSearchParams(Request $request, array $defaults = [], $type)

  an optional and conventional approach of setting search params via query string

  $request : an instance of \Illuminate\Http\Request, query variables in used:

  • range, see getDateRange method
  • start, a valid date string
  • end, a valid date string
  • sort, a mapping property
  • order, value is either desc or asc
  • size, total results to return (max of 10000)

  $defaults : an array of key-value pair of the ff: sort, order, size

  returns Array

• getDateRange($range, $format = null)

  $range : predefined date range values: today, yesterday, last-7-days, this-month, last-month, last-2-months, last-3-months

  $format must be a valid date format, default is null which will return a DateTime instance

  returns Array

• setAggregationDailyDateRanges($start, $end, $format = null)

  $format must be a valid date format, default is null which will return a DateTime instance

  returns Array

• defaultAggregationNames

  returns Array

• defaultIndex

  returns String

• defaultType

  returns String

• defaultTimeFilterField

  returns String

• setSearchQueryFilters(Collection $query, array $bool_clauses = [], $type = null)

  returns Array

• setBoolQueryClause(Collection $query, array $properties, $context, $occur, callable $callback = null)

  returns Array

• getMappingPropertiesByDataType(Collection $properties, $data_type)

  returns Array

• getMappingProperties($type = null)

  returns Collection

• indexDocument(array $body, $type = null, $index = null)

  returns Array

• getDocument($id, $type, $index)

  returns Array

• updateDocument(array $fields, $id, $type = null, $index = null)

  returns Array

• deleteDocument($id, $type = null, $index = null)

  returns Array

• getSettings($index = null)

  returns Array

• updateSettings(array $settings, $index)

  returns Array

• getMappings($index, $type)

  returns Array

• updateMappings(array $properties, $type, $index)

  returns Array

• createIndex(array $mappings, array $settings, $index)

• getIndex($index = null)

  returns Boolean

• deleteIndex($index)

  returns Array

NOTE: All methods of the elasticsearch client are now supported.

Limitations

• Supported data types in search method are:

  • keyword
  • text
  • array
  • integer
  • boolean
  • ip
