**安装教程，网上都可以查询到。这里只简单文字介绍，详细步骤可私信我**
1.下载安装JDK
下载地址https://www.oracle.com/technetwork/java/javase/downloads/index.html
2.配置 JAVA_HOME环境变量
3.打开命令行窗口，输入java -version查看JDK版本 出现版本号 安装成功
4.下载安装elasticsearch
下载地址https://www.elastic.co/downloads
5.配置Path环境变量
*6.打开命令行窗口 执行命令 elasticsearch -d 启动elasticsearch*
7.浏览器打开 http://localhost:9200 出现详细信息 安装成功
8.安装Elasticsearch-Head
elasticsearch-head是一个用于浏览ElasticSearch集群并与其进行交互的Web项目
GitHub托管地址：https://github.com/mobz/elasticsearch-head下载并解压：
9.使用cnpm安装，这样速度会快一些 cnpm的安装方法：
npm install -g cnpm --registry=https://registry.npm.taobao.org
*10.npm run start 启动成功后，可通过http://localhost:9100进行访问*
11.由于跨域（Elasticsearch位于9200端口），需要添加配置： E:\elasticsearch-7.1.0\config\elasticsearch.yml中
#新添加的配置行
http.cors.enabled: true
http.cors.allow-origin: "*"
1.首先我们要先连接Es
<?php
namespace App\Http\Controllers;
use App\Models\Article;
use Elasticsearch\ClientBuilder;
class Text extends Controller
{
//受保护的：只能自己和自己的子类调用
protected $es;
//构造函数的作用：实例化类的时候自动调用，执行每个方法前都会自动执行一次
public function __construct()
{
//连接es
$this->es = ClientBuilder::create()->setHosts(['localhost:9200'])->build();
}
//创建索引（类似于创建数据库）
public function createIndex(){
//设置参数
//index表示索引名称，类似于数据库名称
$params = [
'index'=>'zg4',
'body'=>[
'mappings'=>[
'properties'=>[//汇总字段的
'title'=>[
'type'=>'text',
"analyzer" => "ik_max_word",
"search_analyzer" => "ik_max_word"
]
]
]
]
];
$this->es->indices()->create($params);
}
//添加文档（给数据库的某张数据表添加数据）
public function addDoc(){
$params = [
'index'=>'zg3',//类似于数据库名称
'type'=>'article',//类似于数据表名称(不需要创建的，直接指定就可以了)
'id'=>1,//当前要添加的数据的主键id（自己指定的）
'body'=>['id'=>1,'name'=>'zhangsan','sex'=>1]//数据
];
$res = $this->es->index($params);
dump($res);
}
//修改文档(给数据库的某张表修改数据)
public function updateDoc(){
$params = [
'index'=>'zg3',
'type'=>'article',
'id'=>1,
'body'=>[
//修改的内容
'doc'=>['name'=>'张三']
]
];
$res = $this->es->update($params);
dump($res);
}
//删除文档（根据id删除某个数据库下的某张表下的内容）
public function deleteDoc(){
try {
$params = [
'index'=>'zg3',
'type'=>'article',
'id'=>1
];
$this->es->delete($params);
return json(['code'=>0,'msg'=>'删除成功']);
}catch (\Exception $e){
return json(['code'=>1,'msg'=>'删除失败']);
}
}
//批量添加文档
public function addDocAll(){
$data = Article::select();
$data = collection($data)->toArray();
foreach ($data as $k=>$v){
$params = [
'index'=>'zg4',//类似于数据库名称
'type'=>'_doc',//类似于数据表名称(不需要创建的，直接指定就可以了)
'id'=>$v['id'],//当前要添加的数据的主键id（自己指定的）
'body'=>$v//数据
];
$res = $this->es->index($params);
}
}
//es搜索
public function esSearch(Request $request)
{
$word = $request->get('keyName');
if (empty($word)) {
$data = Housing::with(['HouOtt', 'HouPay', 'HouSet', 'HouType'])->get()->toArray();
return response()->json(['code' => 1, 'msg' => 'word参数不能为空', 'data' => $data]);
}
$page = $request->get('page', 1);//接收当前页，默认值是1
$size = config('pagesize');//每页显示条数
$from = ($page - 1) * $size;//偏移量
$params = [
'index' => 'index',
'body' => [
//执行
'query' => [
//匹配
'match' => [
'f_name' => $word
]
],
'highlight' => [
'pre_tags' => ["<span style='color: red'>"],
'post_tags' => ['</span>'],
'fields' => [
'f_name' => new \stdClass()
]
]
],
'size' => $size,//每页显示的条数
'from' => $from//偏移量
];
$res = $this->es->search($params);
$data = $res['hits']['hits'];
foreach ($data as $k => $v) {
$data[$k]['_source']['f_name'] = $v['highlight']['f_name'][0];
}
$data = array_column($data, '_source');
return response()->json(['code' => 0, 'msg' => '成功', 'data' => $data]);
}
}
——-更新——
框架安装:composer require elasticsearch/elasticsearch
elasticsearch -d 启动elasticsearch/bin/elasticsearch.bat 9200
命令行 切换到head 执行npm run start
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Elasticsearch\ClientBuilder;
//use Illuminate\Http\Request;
class EsController extends Controller
{
//私有的静态属性
private static $EsClient = false;
//私有的构造方法
private function __construct()
{
}
//3.私有的克隆方法
private function __clone()
{
}
//公有的静态方法
public static function getIntance()
{
if (self::$EsClient == false) {
self::$EsClient = ClientBuilder::create()->build();
}
return self::$EsClient;
}
public function escreate()
{
$params = [
'index' => 'gao1103s'//库名
];
// Create the index
$client = ClientBuilder::create()->build();
$response = $client->indices()->create($params);
//指定分词
$client = ClientBuilder::create()->build();
$params = [

]
];
// Create the index with mappings and settings now
$response = $client->indices()->create($params);
}
public function addition()
{

$data = WechatShop::all();
$body = [];
foreach ($data as $v) {

$params['body'][] = array(

'shop_price' => $v['shop_price'],
);
}
$response = $client->bulk($params);
print_r($response);
}
public function essearch(Request $request)
{
$search_field = "shop_name";//搜索的字段
$word = $request->input('word', '');//接收关键字
$page = $request->input('page', 1);//接收当前页（如果没接收到，默认是1）
$size = $request->input('size', 5);;//每页显示条数
$limit = ($page - 1) * $size;//偏移量
$client = ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();//创建es实例
//设置查询的条件
if (empty($word)) {
$body = [
];
} else {
$body = [
//查询内容
'query' => [
'match' => [//匹配
$search_field => $word//匹配字段
]
],
'highlight' => [//高亮
'pre_tags' => ["<em style='color: red'>"],//样式自己写
'post_tags' => ["</em>"],
'fields' => [
$search_field => new \stdClass()
]
]
];
}
$params = [
'index' => 'gao1103s',//索引（类似于库）
'body' => $body,
'size' => $size,//每页显示条数
'from' => $limit//偏移量
];
$results = $client->search($params);//es搜索
if (!empty($word)) {
foreach ($results['hits']['hits'] as $k => $v) {
$results['hits']['hits'][$k]['_source'][$search_field] = $v['highlight'][$search_field][0];
}
}
$data = array_column($results['hits']['hits'], '_source');
$arr['page'] = $page;//当前页
$arr['total'] = $results['hits']['total']['value'];//总条数
$arr['last_page'] = ceil($results['hits']['total']['value'] / $size);//总页数
$arr['data'] = $data;//数据
return response()->json($arr);
}
}小程序页面不解析
