1) tener instalado elasticsearch
instalar
descargar el zip desde
https://www.elastic.co/guide/en/elasticsearch/reference/current/zip-windows.html
extraer here
ir a la carpeta bin y ejecutar el archivo de lotes: elasticsearch.bat
para verificar que esta arriba el servicio, abrir en el browser
http://localhost:9200/
deberia mostrar algo asi:
// 20190310223923
// http://localhost:9200/
{
"name": "6QTn43S",
"cluster_name": "elasticsearch",
"cluster_uuid": "JELK0mCSRfarxHyCvTDGqQ",
"version": {
"number": "6.6.1",
"build_flavor": "default",
"build_type": "zip",
"build_hash": "1fd8f69",
"build_date": "2019-02-13T17:10:04.160291Z",
"build_snapshot": false,
"lucene_version": "7.6.0",
"minimum_wire_compatibility_version": "5.6.0",
"minimum_index_compatibility_version": "5.0.0"
},
"tagline": "You Know, for Search"
}
nota: en el momento de escribir esta entrada la version de ES era 6.6.1
2) crear un proyecto web
en xampp/htdocs crear un directorio p.e llamado elastic_php
editar el archivo xampp/apache/conf/httpd-vhosts.conf
agregar
<VirtualHost *:80>
ServerName elastic_php.local
DocumentRoot "C:/xampp729/htdocs/elastic_php"
</VirtualHost>
luego editar
C:\Windows\System32\drivers\etc\hosts
y agregar
127.0.0.1 elastic_php.local
asi podemos podemos llamar a la aplicacion con la sgt url
http://elastic_php.local
2)instalar el cliente php de elasticsearch
( https://github.com/elastic/elasticsearch-php )
crear en la raiz del proyecto creado el archivo
composer.json
con el sgt contenido
{
"require": {
"elasticsearch/elasticsearch": "~6.0"
}
}
desde la consola ejecutar
composer install
3)crear un documento
crear en la raiz del proyecto el archivo index.php
<?php
require 'vendor/autoload.php';
$client = Elasticsearch\ClientBuilder::create()->build();
$params = [
'index' => 'my_index',
'type' => 'my_type',
'id' => 'my_id',
'body' => ['testField' => 'abc']
];
$response = $client->index($params);
print_r($response);
la salida seria algo como:
Array
(
[_index] => my_index
[_type] => my_type
[_id] => my_id
[_version] => 1
[result] => created
[_shards] => Array
(
[total] => 2
[successful] => 1
[failed] => 0
)
[_seq_no] => 0
[_primary_term] => 1
)
los capos obligatorios son index, type y body.
si no se envia id, este se generara
$params = [
'index' => 'my_index',
'type' => 'my_type',
'body' => ['nombre' => 'juan']
];
$response = $client->index($params);
print_r($response);
esta seria la salida:
Array
(
[_index] => my_index
[_type] => my_type
[_id] => BlmuamkB863YvXXYJ9xk
[_version] => 1
[result] => created
[_shards] => Array
(
[total] => 2
[successful] => 1
[failed] => 0
)
[_seq_no] => 2
[_primary_term] => 1
)
4) obtener un documento
$params = [ 'index' => 'my_index', 'type' => 'my_type', 'id' => 'my_id' ]; $response = $client->get($params); print_r($response);
obtendriamos algo asi:
Array
(
[_index] => my_index
[_type] => my_type
[_id] => my_id
[_version] => 2
[_seq_no] => 1
[_primary_term] => 1
[found] => 1
[_source] => Array
(
[testField] => abc
)
)
5)
obtener solo los datos del documento (sin la metadata)
$response = $client->getSource($params);
print_r($response);
obtendriamos algo asi:
Array
(
[testField] => abc
)
6) Buscar un documento
$params = [
'index' => 'my_index',
'type' => 'my_type',
'body' => [
'query' => [
'match' => [
'nombre' => 'israel'
]
]
]
];
$response = $client->search($params);
Array
(
[took] => 5
[timed_out] =>
[_shards] => Array
(
[total] => 5
[successful] => 5
[skipped] => 0
[failed] => 0
)
[hits] => Array
(
[total] => 1
[max_score] => 0.2876821
[hits] => Array
(
[0] => Array
(
[_index] => my_index
[_type] => my_type
[_id] => 1
[_score] => 0.2876821
[_source] => Array
(
[nombre] => israel
)
)
)
)
)
