Lelastico - easier elastic search for Laravel

Introduction

Focus of this library is to make it easier to manage elastic indices (wit mappings / settings), create reusable query building (manual or from request).

• Adds ability to manage elasticsearch indices with wrapper class which will help to you create/update index write documents (with bulk mode) etc.
• Adds ability to create a query builder with query filters for each index.
• Adds ability to build a query builder from request data (reusable component).

Requirements

• Composer
• PHP 7.4+

Installation

1. Add custom repository to composer.json

2. Install via composer

3. Add the service provider (Laravel 5.4 and below - supports Auto discovery)

Dependencies

• erichard/elasticsearch-query-builder - at this moment forked version with additional functions.
• elasticsearch/elasticsearch, version 7 and above (tested with 7.5).

Usage

Set elastic hosts

For development, you can use default value in the config without password: localhost:9200

Use ELASTICSEARCH_HOSTS environment for setting elastic search hosts. Format.

Mapping types constants

Property mappings types using constants like:

• MappingTypes::KEYWORD
• MappingTypes::TEXT
• MappingTypes::TEXT_WITH_KEYWORD
• MappingTypes::SHORT
• MappingTypes::SHORT_WITH_KEYWORD
• MappingTypes::LONG
• MappingTypes::LONG_WITH_KEYWORD
• MappingTypes::INTEGER
• MappingTypes::INTEGER_WITH_KEYWORD
• MappingTypes::DATE
• MappingTypes::BOOLEAN
• MappingTypes::FLOAT
• MappingTypes::textWithAnalyzer(string $analyzer, string $searchAnalyzer), builds

Adding indices

1. Create your indices by extending AbstractElasticIndex and implementing createIndexName for elastic index

   • Implement propertyMappings for custom mappings.

   • Implement settings for custom index settings

2. Create or update lelastico.php config with indices classes.

3. Update or create indices in elastic (stores settings / mapping) using php artisan elastic:indices

Sorting

By default we are sorting by _id after any HasSorting logic to ensure that pagination is correct.

You can turn this feature by using $builder->setSortById(false);

To enable sortable behavior add HasSorting trait to your instance of AbstractBuilder and implement method allowedSortFields.

With sorting enabled you can sort the results using sort request query parameter. This parameter accepts list of fields for sorting in format {field_name}:{sort_direction}.

Available directions for sorting are asc and desc and if not specified the default sort direction is set to asc.

Examples:

sort[]=goals

sort[]=goals:asc&sort[]=minutes:desc

Configuration

• log_measurement Logs every query to log (default false). You can use ELASTICSEARCH_LOG_MEASUREMENT env.
• log_debug Debug logs every query data to a log (true in local environment). You can use ELASTICSEARCH_LOG_DEBUG env.
• service Enables to change available indices (implement IndicesServiceContract or extend IndicesService)
• prefix Used prefix for index names - uses APPNAME and replace '-' to '', converts name to slug variant.
• hosts A list of IPS for your elastic search - https://www.elastic.co/guide/en/elasticsearch/client/php-api/current/configuration.html. Use ; separator. Default localhost:9200.

TODO

• improve documentation
• add make console.
