1：前提条件是下载es，开启es,这里我上一篇文章已经总结过啦，就不过多解释了
laravel 进行安装elasticsearch 组件
composer require elasticsearch/elasticsearch.在要使用的地方引入ES
use Elasticsearch\ClientBuilder;2：在 app/http/controllers/service 新建 Elasticsearch .php 直接封装代码
<?php

}
调用封装的代码
（1）新增索引（表名）
/**
* 显示资源列表
*/
public function index()
{
//创建索引 索引名称不能重复 否则报错
$es = new ElasticsearchServier('ElasticsearchServier');
// 你要创建的索引名称
$indexNmae = 'es_test';
$result = $es->create_index($indexNmae);
return response()->json(['code' => 200, 'messages' => '索引创建成功', 'data' => $result]);
}走路由
//es 的创建
Route::get('es_index','ShowDataController@index');
（2）添加数据
/**
* 添加数据
*/
public function create()
{
// 参数 相当于$request->post（‘title’）
$title = '老人与海';
$content = '老人与海的文章内容';
$data = [
'title' => $title,
'content' => $content
];
try {
//添加至数据库中,并将id返回
$id = Title::insertGetId($data);
//将数据添加到es中
$es = new ElasticsearchServier('ElasticsearchServier');
$params = [
//索引名
'index' => "title",
//相当于数据库
'type' => "es",
//id
'id' => $id,
"body" => [
"title" => $data['title'],
"content" => $data['content'],
]
];
$es->add_doc($params);
} catch (Exception $exception) {
return response()->json(['code' => 200, 'messages' => '数据添加成功', 'data' => $id]);
}
return response()->json(['code' => 200, 'messages' => '数据添加成功', 'data' => $id]);
}走路由
// es 添加
Route::get('es_create','ShowDataController@create');
（3）查询一条数据
/**
* 查询一条数据
*/
public function edit(Request $request)
{
//要搜索的id值
$id = 3; //$request->get('id');
$es = new ElasticsearchServier('ElasticsearchServier');
//查询数据
$edit = $es->get_doc($id, 'title', 'es');
return response()->json(['code' => 200, 'messages' => '索引创建成功', 'data' => $edit]);
}走路由
// es 详情
Route::get('es_edit','ShowDataController@edit');
（4）搜索
/**
* 搜索
*/
public function search_doc()
{
$where = '与海';
$es = new ElasticsearchServier('ElasticsearchServier');
$index_name = "title";
$type_name = "es";
$body = [
'query' => [
'bool' => [
'should' => [
[
'match' => [
// 搜索的字段名
'title' => [
//搜索的关键字
'query' => $where,
'boost' => 4, // 权重大
]
],
],
[
'match' => [
'content' => [
'query' => $where,
'boost' => 3, // 权重大
]
],
],
],
]
]];
$response = $es->search_doc($index_name, $type_name, $body);
$data = array_column($response, "hits");
$data = array_column($data[0], "_source");
foreach ($data as $key => &$val) {
$val['title'] = str_replace($where, "<span style='color: red'>$where</span>", $val['title']);
}
//可以将数据发送到视图
print_r($data);
}走路由
// es 搜索
Route::get('es_search','ShowDataController@search_doc');
（5）修改
/**
*修改
*/
// 根据id修改es中的数据
public function update()
{
$id = 3; //$request->get('id');
$title ='6100万颗心的共同记忆 再次C位亮相，闪耀全球！' ; //$request->get('title');
$content = '刚刚过去的这个清明节，与往年一样，有人凭寄哀思，有人缅怀忠魂。但也有一些瞬间'; //$request->get('id');
$es = new ElasticsearchServier('ElasticsearchServier');
$params = [
'index' => "title",
'type' => "es",
'id' => $id,
"body" => [
"doc" => [
"title" => $title,
"content" => $content
]
]
];
$result=$es->update_doc($params);
return response()->json(['code' => 200, 'messages' => '数据修改成功', 'data' => $result]);
}走路由
// es 修改
Route::get('es_update','ShowDataController@update');
查看是否搜索成功
（6）查询全部数据
/**
*获取文档 查询全部的数据
*/
public function selects()
{
$es = new ElasticsearchServier('ElasticsearchServier');
$data = $es->search_doc('title','es');
return response()->json(['code' => 200, 'messages' => '数据查询', 'data' => $data]);
}走路由，并访问
//es 展示
Route::get('es_select','ShowDataController@selects');
