elasticsearch分词插件安装

官方地址：https://github.com/medcl/elasticsearch-analysis-ik

两种安装方式：

1. 进入elasticsearch-6.5.0/plugins/然后

mkdir ik 
cd ik
 wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.5.0/elasticsearch-analysis-ik-6.5.0.zip
unzip elasticsearch-analysis-ik-6.5.0.zip
rm -rf elasticsearch-analysis-ik-6.5.0.zip

2. 或者按照如下方式安装，进入elasticsearch-6.5.0

./bin/elasticsearch-plugin install  https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.5.0/elasticsearch-analysis-ik-6.5.0.zip

安装完之后测试分词效果

$params = [
            'body' => [
               'text' => '天天敲代码非常高兴',
                'analyzer'=>'ik_max_word' //ik_max_word 精细  ik_smart 粗略
            ]
        ];
      $res =  $esclient->indices()->analyze($params);
      print_r($res);

使用分词插件：(php代码)

创建空索引(必须是新索引名称)

$params = [
            'index' => 'my_index_user1',
        ];
  $res =  $esclient->indices()->create($params);

创建映射

   $params = [
            'index' => 'my_index_user1',
            'type' => 'my_type_user1',
            'body' => [
                'my_type_user1' => [
                    '_source' => [
                        'enabled' => true
                    ],
                    'properties' => [
                     
                        'userinfo' => [
                            'type' => 'text', // 字符串型
                            'analyzer'=>'ik_max_word', //ik_max_word 最细粒度拆分 ik_smart最粗粒度拆分
                            'search_analyzer'=> 'ik_max_word'
                        ]
                      
                    ]
                ]
            ]
        ];

        $res = $esclient->indices()->putMapping($params);

生成索引(可以使用前面批量生成或者单个生成的方法)索引名必须为 my_index_user1

 $params = [
                'index' => 'my_index_user1',
                'type' => 'my_type_user1'
            ];
        $addpar=[];
        foreach($data as $key=>$val){
            $params['body'][]= ['index' => [ '_id' => $val->id]];
            unset($val->id);
            foreach($val as $k=>$v){
                $addpar[$k]=$v;
            }
            $params['body'][]=$addpar;
        }
        $res = $esclient->bulk($params);
        print_r($res);

搜索

$search_params = [
            'index' => 'my_index_user1',
            'type' => 'my_type_user1',
            'body' => [
                'query' => [
                    'match' => [
                        'userinfo' => '访问目录'
                    ]
                ],
                //设置高亮
                "highlight" => [
                    "pre_tags" => [
                        '<span style="color:red">'
                    ],
                    "post_tags" => [
                       '</span>'
                       
                    ],
                    'fields'=> [
                        'userinfo' => new \stdClass()
                    ]  
                ]
            ]
        ];
        $res = $esclient->search($search_params);
        print_r($res);

不同查询方式，精确匹配(匹配到所有的关键词)
修改match部分
//有一个关键词出现即可

  'match' => [
                        'userinfo' => '访问目录'
                    ]

//所有关键词都必须出现 可以不连续

'match' => [
                        'name' => ['query' => '大蛋糕','operator' => 'AND']   
        ]

//必须完全匹配

 'query' => [
                    'match_phrase' => [
                        'name' =>  '可以查看'
                    ]
]

//通配符查询

 'query' => [
                    'wildcard' => [
                        'name' =>  '*user*'
                    ]
                ]

//分页查询

 'body' => [
                'from' => 4,
                'size' => 3,
                'query' => [
'match_phrase' => [
                        'name' =>  '可以查看'
                    ]

//正则查询

 'query' => [
                    'regexp' => [
                        'ints' =>  '135.*'
                    ]
                ]
