gofound 試用

https://github.com/sea-team/gofound 是純 go 實現的一個類 es 的簡易版本搜索引擎。支持全文檢索引擎基於平衡二叉樹 + 正排索引、倒排索引實現可支持億級數據，毫秒級查詢。使用簡單，使用 http 接口。

安裝

go get && go build

查看 admin 後臺

查看 api 接口

http://127.0.0.1:8080/api/
{
state: true,
message: "success",
data: "Welcome to GoFound"
}

gofound 啓動之後，會監聽一個 TCP 端口，接收來自客戶端的搜索請求。處理 http 請求部分使用 gin 框架。如果不指定，默認數據庫爲 default。

插入數據

 % curl -H "Content-Type:application/json" -X POST --data '{"id":88888,"text":"深圳北站","document":{"title":"阿森松島所445","number":223}}' 'http://127.0.0.1:8080/api/index?database=default'
{"state":true,"message":"success"}

批量插入

curl -H "Content-Type:application/json" -X POST --data '[
  {
    "id": 88888,
    "text": "深圳北站",
    "document": {
      "title": "阿森松島所445",
      "number": 223
    }
  },
  {
    "id": 22222,
    "text": "北京東站",
