//可以添加字段，但原有字段是不能修改类型的，原因是：
//一个字段的类型修改以后，那么该字段的所有数据都需要重新索引。Elasticsearch底层使用的是lucene库，字段类型修改以后索引和搜索要涉及分词方式等操作，不允许修改类型是符合lucene机制的。
// $result = $es->updMapping($properties);
echo '';

exit;
}
}
yii2的操作类
1 引入elasticsearch操作类
composer.json的require中添加
"yiisoft/yii2-elasticsearch": "~2.0.0"
composer update
2 config/web.php的components中添加
'components' => [
...
'elasticsearch' => [
'class' => 'yii\elasticsearch\Connection',
'nodes' => [
['http_address' => '192.168.163.128:9200']
],
'autodetectCluster' => false
],
...
],
3 新建model类
namespace app\modules\study\models;
use yii\elasticsearch\ActiveRecord;
class Es extends ActiveRecord
{
public static $currentIndex;
# 定义db链接
public static function getDb()
{
return \Yii::$app->get('elasticsearch');
}
# 索引
public static function index()
{
return 'lib';
}
# 类型
public static function type()
{
return 'books';
}
/**
* Create this model's index
*/
public static function createIndex()
{
$db = static::getDb();
$command = $db->createCommand();
$command->createIndex(static::index(), [
'settings' => [ 'index' => ['refresh_interval' => '1s'] ],
'mappings' => static::mapping(),
//'warmers' => [ /* ... */ ],
//'aliases' => [ /* ... */ ],
//'creation_date' => '...'
]);
}
/**
* Delete this model's index
*/
public static function deleteIndex()
{

}
public static function updateRecord($productid, $columns){
try {

foreach($columns as $key => $value){
$record->$key = $value;
}
return $record->update();
}catch (\Exception $e){

}
}
//删除记录
public static function deleteRecord($productid){
try {

return true;
}catch (\Exception $e){

}
}
//保存数据(添加 || 更新)
public function saveRecord($data){
//加载数据

//遍历数据到对象
foreach ($data['Es'] as $key => $value) {

}
# 属性
public function attributes()
{
$mapConfig = self::mapConfig();
return array_keys($mapConfig['properties']);
}
public function rules()
{
return [
[["productid","title"],'required']
];
}
# mapping配置
public static function mapConfig()
{
return [
'properties' => [
'productid' => ['type' => 'double'],
'title' => ['type' => 'string','analyzer'=>'ik'],
'price' => ['type' => 'double']
]
];
}
public static function mapping()
{
return [
static::type() => self::mapConfig(),
];
}
/**
* Set (update) mappings for this model
*/
public static function updateMapping()
{
$db = self::getDb();
$command = $db->createCommand();
if (!$command->indexExists(self::index())) {

}
public static function getMapping()

}
4 控制器中操作
namespace app\modules\study\controllers;
use yii\web\Controller;
use app\modules\study\models\Es;
class EsController extends Controller
{
//查询
public function actionTest(){
$keyword = "java2";
$res = Es::find()->query([
"term" => ['title'=>'java'],
//"multi_match" => [
//"query" => $keyword,
// "fields" => ["title"] //检索属性
//],
])->asArray()->all();
echo '';
print_r($res);
exit;
}
//创建 或更新
public function actionAdd(){
$ESArray = [
'Es' => [
'productid' => '4',
'title' => 'php2',
'price' => '22'
]
];
$es = new Es();
if(!$es->saveRecord($ESArray)){
throw new \Exception("操作失败");
}
echo "操作成功";
}
//删除
public function actionDelete($id){
$es = new Es();
if(!$es->deleteRecord($id)){
throw new \Exception("删除失败");
}
echo "操作成功";
}
}
