A Laravel Scout Driver for Elasticsearch 5.x
ElasticScout is a Laravel Scout Elasticsearch 5.x compatible engine. It makes critical changes to the old Elasticseach Scout Engine, as well as adds new functionality.
The ElasticScout engine includes an Elasticsearch Query Builder which can be used to create elaborate custom queries and aggregations, allowing full use of Elasticsearch within the Laravel/Scout Paradigm.

- Run composer require command
composer require brokerexchange/elasticscout - Configure Elasticsearch Host (default: localhost:9200)
ELASTICSEARCH_HOST='elastic1.host.com:9200,elastic2.host.com:9200'- Add trait to desired model
use ElasticScout\Searchable; //create search/query object
$search = $article->search()
->boolean()
->should(DSL::match('title',$request->input('query')))
->should(DSL::match('body',$request->input('query')))
->filter(DSL::term('published', 1))
->aggregate(Agg::terms('categories', 'category.name'));
//fire the search
$articles = $search->paginate();
//retrieve aggregation results
$categories = $search->aggregation('categories');You may set a custom mapping by simply defining a "mapping" method on your model.
public function mappings()
{
return [
$this->searchableType() => [
'properties' => [
'name' => [
'type' => 'text',
'fields' => [
'keyword' => [
'type' => 'keyword',
],
'autocomplete' => [
'type' => 'text',
'analyzer' => 'autocomplete',
'search_analyzer' => 'autocomplete_search',
],
],
],
]
]
]
}You may create custom settings and analyzers by creating a "settings" method on the model.
public function settings()
{
return [
'index' => [
'analysis' => [
'analyzer' => [
'autocomplete' => [
'tokenizer' => 'autocomplete',
'filter' => [
'lowercase',
],
],
'autocomplete_search' => [
'tokenizer' => 'lowercase',
],
],
'tokenizer' => [
'autocomplete' => [
'type' => 'edge_ngram',
'min_gram' => 1,
'max_gram' => 15,
'token_chars' => [
'letter'
]
]
]
],
],
