Elastic Commander

This a simple and easy to use wrapper for the official low-level Elasticsearch PHP Client.

It simplifies the work with Elasticsearch API by offering a lot of helper methods for managing indices, adding and updating documents and searching the index.

Installation

Via Composer

$composer require iivannov/elastic-commander

---

Usage

Initialization

Minimum required (will work with default host - localhost:9200)

$commander = new Commander('YourIndexName');

With a list of hosts

$hosts = [
    '192.168.1.1:9200',         // IP + Port
    '192.168.1.2',              // Just IP
    'mydomain.server.com:9201', // Domain + Port
    'mydomain2.server.com',     // Just Domain
    'https://localhost',        // SSL to localhost
    'https://192.168.1.3:9200'  // SSL to IP + Port
];

$commander = new Commander('YourIndexName', $hosts);

With a custom handler

$handler = new MyCustomHandler();
$commander = new Commander('YourIndexName', $hosts, $handler);

N.B. Each instance of the Commander works with the index name specified when initializing it. All actions and queries will be executed on this index. If you want to set a new index name to work with use:

$commander->reset('NewIndexName');

Index

1. Create the index

$commander->index()->create();

2. Delete the index

$commander->index()->delete();

3. Reset the index

A helper method that will reset the index by deleting it and creating it again.

$commander->index()->reset();

4. Optimize the index

// Not finished

$commander->index()->optimize();

5. Statistics about the index

// Not finished

$commander->index()->stats();

---

Mapping

1. Put Mapping

$commander->mapping($mapping);

---

Document

1. Check if document exists by id

$commander->document('SomeDocumentType')->exists($id);

2. Get document by id

$commander->document('SomeDocumentType')->get($id);

3. Add document

In current version the add method expects an ID for the document.

$commander->document('SomeDocumentType')->add($id, $parameters);

4. Update document

$commander->document('SomeDocumentType')->add($id, $parameters);

---

Search

Searching is done by passing a raw query array or by using a custom criteria class. After the query you have the option to get: the full response, only the ids, a map of the results or the total count.

1. Raw Query

$result = $commander->search('SomeDocumentType')->query($query, $sort, $size, $from);

2. Criteria Query

$result = $commander->search('SomeDocumentType')->criteria($criteria);

Result

After running either a raw query or one with a criteria class you can use one of the helper methods for manipulating the result response.

1. Return ElasticSearch raw response

$result->response();

2. Return total number of results

$result->total();

3. Return an array of IDs for the found hits

$result->ids();

3. Return an array of objects for the found hits

The key will be the _id of the hit and the value will be an stdClass of the _source

$result->hits();
