创建search-ui项目
npm install -g create-react-app
# 创建名为doc_index的项目
create-react-app doc_index --use-npm
cd doc_index
npm install --save elastic/react-search-ui elastic/search-ui-app-search-connector elastic/search-ui-elasticsearch-connector启动search-ui项目
npm start创建api_key
登录kibana进入到/app/management/security/api_keys/创建一个api_key并记录api_key.
创建索引
登录kibana的dev_tools创建和设置索引
# 创建索引
PUT /doc_index# 设置索引属性
PUT /doc_index/_mapping
{properties:{title:{type:text,fields:{suggest: {type: search_as_you_type}}},category:{type:text},url:{type:text}}
}# 设置查询返回的最大条数
PUT /doc_index/_settings
{index : {max_result_window: 500000}
}导入数据
# 插入单条数据
POST /doc_index/_bulk
{index:{}}
{title:test,category:test,url:http://localhost:3000}## 批量插入
POST /doc_index/_bulk
{index:{}}
{title:test2,category:test,url:http://localhost:3001}
{index:{}}
{title:dir,category:test,url:http://localhost:3002}
{index:{}}
{title:ddssd,category:test,url:http://localhost:3003}
{index:{}}
{title:测试,category:test,url:http://localhost:3004}当然也可以用命令行插入如使用curl命令
curl --username username:password -H Content-Type: application/json -XPOST 192.168.56.130:9200/bank/account/_bulk?pretty --data-binary test.json其中–username指定elasticsearch的用户名和密码test.json的内容如下
{index:{}}
{title:test2,category:test,url:http://localhost:3001}
{index:{}}
{title:dir,category:test,url:http://localhost:3002}
{index:{}}
{title:ddssd,category:test,url:http://localhost:3003}
{index:{}}
{title:测试,category:test,url:http://localhost:3004}完整数据插入命令如下 PUT /doc_index/_mapping
{properties:{title:{type:text,fields:{suggest: {type: search_as_you_type}}},category:{type:text},url:{type:text}}
}PUT /doc_index/_settings
{index : {max_result_window: 500000}
}GET /doc_index/_searchPOST /doc_index/_bulk
{index:{}}
{title:test2,category:test,url:http://localhost:3001}
{index:{}}
{title:dir,category:test,url:http://localhost:3002}

{title:测试,category:test,url:http://localhost:3004}完善search-ui
search-ui下载下来之后还没有绑定数据此时还需要修改app.js来进行适配。
app.js需更改成
// Step #1, import statements
import React from react;
// 这里需要注意app和网页的接口名称不一样
import ElasticsearchAPIConnector from elastic/search-ui-elasticsearch-connector;
import {PagingInfo,ResultsPerPage,Paging,SearchProvider,Results,SearchBox,Sorting
} from elastic/react-search-ui;
import { Layout } from elastic/react-search-ui-views;
import elastic/react-search-ui-views/lib/styles/styles.css;// Step #2, The connector
const connector new ElasticsearchAPIConnector({host: http://elasticsearch:9200, // elasticsearch的地址apiKey: WjUxNVpZc0JTb3pYN2J6cEdqRHQ6R3Y0all0R1dTai1LSjhqMGc5THFVdw, // elasticsearch 的登录秘钥在kibana上生成index: doc_index // 要访问的索引的地址
});// Step #3: Configuration options
const configurationOptions {searchQuery: {search_fields: {title: {weight: 3},url: {},category: {}},result_fields: {title: {snippet: {}},url: {snippet: {}},category: {snippet: {}}}},apiConnector: connector,alwaysSearchOnInitialLoad: true
};// step4 show result
export default function App() {return (SearchProvider config{configurationOptions}div classNameAppLayoutheader{SearchBox /}// 要展示的标题和标题对应的连接bodyContent{Results titleFieldtitle urlFieldurl /}bodyHeader{PagingInfo /ResultsPerPage //}bodyFooter{Paging /}//div/SearchProvider);
}还可以修改一下public下面的title标签修改成自己的项目标签。如
titledoc_index/title
