Elasticsearch-PHP 7 Return All documents of a given mapping

Question

Summary

Failing to get any/all documents from my ElasticSearch instance using the ElasticSearch-PHP 7 package.

When I run Curl query, works just fine. So I know I have bulk inserted the documents properly. Meaning that documents do exist.

Curl Success

Curl Call

curl -X GET -u elastic:changeme 'ltr-elasticsearch:9200/experiences_1621701804/region/_search?pretty'

Updated Possible Solution?

Rookie move, I should have compared versions. There is a version mapping for the package elasticsearch/elasticsearch.

https://www.elastic.co/guide/en/elasticsearch/client/php-api/current/installation.html

I am currently on v 5.2 of elasticsearch/elasticsearch.

It looks like v5 does not support match_all? Which to me is really odd. I would think a fundamental feature would be to get ALL documents. I get it's a search tool, and maybe it just focused on filtered search results. And it's possible it just handles it in a different way undocumented.

v5: https://www.elastic.co/guide/en/elasticsearch/client/php-api/5.x/_match_query.html

I am currently locked out of my work VPN and unable to upgrade packages to test. Will follow up once I am able.

Answer 1

remove body will return all document

 $params = [
        'index' => 'your_index',
    ];
    $response = $this->elasticsearch->search($params);
    dump($response);
