laravel:使用ik中文分词访问es

一，php代码

1，用composer安装elasticsearch库

[lhdop@blog dignews]$ composer require elasticsearch/elasticsearch 

2, 创建索引:

    //创建索引
    public function create(){

       //初始化一个es
       $client = $this->_init_es();

        $params = [
            'index' => 'gsindex', //索引的名称（mysql的表名）
            'body' => [
                'settings' => [
                    'number_of_shards' => 5,//设置数据的分片数，默认为5
                    'number_of_replicas' => 0,//备份数，单个es服务器无需备份
                ],
                'mappings' => [
                    'properties' => [
                        'id' => [
                            'type' => 'integer'
                        ],
                        'title' => [
                            'type' => 'text', //text类型，做模糊搜索用
                            'analyzer'=>'ik_max_word',//较细粒度分词，写入数据用  需要安装ik并将ik放入es的plugin中
                            'search_analyzer'=>'ik_smart',//较细粒度分词，查询数据用  需要安装ik并将ik放入es的plugins中
                        ],
                        'content' => [
                            'type' => 'text', //text类型，做模糊搜索用
                            'analyzer'=>'ik_max_word',//较细粒度分词，写入数据用  需要安装ik并将ik放入es的plugin中
                            'search_analyzer'=>'ik_smart',//较细粒度分词，查询数据用  需要安装ik并将ik放入es的plugins中
                        ],
                    ],
                ],
            ],
        ];
        $response = $client->indices()->create($params);

        print_r($response->asArray());

        //return 'Hello, World!'.$msg;
    }

3,索引数据

//多数据索引
    public function mindex(){
     //初始化一个es
       $client = $this->_init_es();

       $d1 = ['id'=>1,'title'=>'北京房产','content'=>'北京房产,天通苑'];
       $d2 = ['id'=>2,'title'=>'沧州房产','content'=>'河北沧州房产,沧县,任丘'];
       $d3 = ['id'=>3,'title'=>'石家庄房产','content'=>'河北石家庄房产,获鹿,正定'];
       $d4 = ['id'=>4,'title'=>'石家庄土地','content'=>'河北石家庄土地,新华,赵县'];

       $data = [$d1,$d2,$d3,$d4];

        foreach ($data as $k => $one) {
            $params = [
                'index' => 'gsindex',
                //'type' => '_doc',
                //'id' => $item->id,
                'body' => [
                    'id' => $one['id'],
                    'title' => $one['title'],
                    'content' => $one['content'],
                ],
            ];
            $rs = $client -> index($params);
            var_dump($rs);
        }

    }

4, 搜索:

     //搜索多个字段
    public function msearch() {
        //初始化一个es
        $client = $this->_init_es();

        //总结:and用must,or用should
        $esWhere = [];
        //如果需要 同时满足多个查询条件（and查询），则复制下面参数，改title为 descs即可
        /*
        $esWhere['bool']['must'] = [
            ['match' => [
                'content' =>'河北'
            ]],
            ['match' => [
                'title' =>'房产'
            ]],
        ];
        */
        //条件之间是or的关系
        $boolshould = [];
        $boolshould['bool']['should'] = [
            ['match' => [
                'content' =>'河北'
            ]],
            ['match' => [
                'title' =>'房产'
            ]],
        ];

        //范围搜索
        $range= ['range' => [
                'id' => [
                    'gte' => 2 // gte 表示大于等于
                ]
            ]];

        //搜索条件：id>=2,且content包含河北或title包含房产
        $esWhere['bool']['must'] = [
            $range,
            $boolshould
        ];


        //按id排序
        $sortOrder = ['id'=>'asc'];

        $where = [
            'index'=>'gsindex',
            'size'=>10,
            'from'=>0,
            //'type'=>'_doc',
            'body' => [
                'query' =>$esWhere,//查询条件
                'sort' =>$sortOrder,//排序条件，注意 添加后 返回结果 无_score值
            ]
        ];

        $client = $this->_init_es();
        $rs = $client->search($where);
        
        $data = $rs->asArray();
        //print_r($rs->asArray());
        $json = json_encode($data);
        echo $json;

        /*
        foreach ($data['hits']['hits'] as $k => $one){
            print_r($one);
        }
        */
    }

 

二，测试效果:

访问搜索页面的结果:

如图:

 

三，查看laravel版本:

[lhdop@blog dignews]$ php artisan --version
Laravel Framework 11.15.0
