微信小程序 ES搜索

先下载es composer

composer require elasticsearch/elasticsearch

先进行判断es中是否有这个索引

$client = ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();
        // 写文档
        $index=['index'=>'title'];
        //判断是否有该索引
        $res=$client->indices()->exists($index);

 没有这个索引添加索引

if($res!=true)
{
    $params = [
        //表名
        'index' => '表名',
        'body' => [
            'settings' => [
                'number_of_shards' => 5,
                'number_of_replicas' => 1
            ],
            'mappings' => [
                '_doc' => [
                    '_source' => [
                        'enabled' => true
                    ],
                    'properties' => [
                        //所需要展示的字符安
                        'name' => [
                            'type' => 'text',
                            'analyzer' => 'ik_max_word',
                            'search_analyzer' => 'ik_max_word'
                        ],
                        'title' => [
                            'type' => 'text',
                            'analyzer' => 'ik_max_word',
                            'search_analyzer' => 'ik_max_word'
                        ]
                    ]
                ]
            ]
        ]
    ];
    $client->indices()->create($params);
}

 添加数据内容

//添加  
$data=$request->input();
        unset($data['_token']);
        $first=Title::create($data);

 $params = [
            'index' => 'title',
            'type' => '_doc',
            'id' => $first->id,
            'body' => [
                'name' => $first->name,
                'title' => $first->title,
            ],
        ];
        $client->index($params);

//搜索内容

public function index(Request $request)
    {
        //连接es服务
        $client = ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();
        $name=$request->input('name');
        //搜索的字段
        if($name)
        {
            $create = [
                'index' => 'title',
                'type' => '_doc',
                'body' => [
                    'query' => [
                        'match' => [
                            'name'=>$name
                        ]
                    ],
                    'highlight' => [//高亮
                        "pre_tags" => [""],
                        "post_tags" => [""],
                        "fields" => [

                    ]
                ],
            ];
            $res=$client->search($create)['hits']['hits'];
            $data=[];
            foreach ($res as $k=>$v){
                $data[$k]['name']=$v['highlight']['name'][0];
                $data[$k]['title']=$v['_source']['title'];
            }

        }else{
            $data=Title::get()->toArray();
        }
       return response()->json(['code'=>200,'msg'=>'请求成功','data'=>$data]);
