Riot 搜索引擎

Go 开源、分布式、简单高效的全文本搜索引擎。

特性

安装/更新

go get -u github.com/go-ego/riot

要求

需要 Go 版本至少为 1.8

依赖

Riot 使用 go module 或 dep 管理依赖. 

go get -u github.com/go-ego/re

re riot

创建 riot 项目 

$ re riot my-riotapp

re run

运行我们创建的 riot 项目, 你可以导航到应用程序文件夹并执行: 

$ cd my-riotapp && re run

使用

先看一个例子（来自 simplest_example.go） 

package main
import (
    "log"
    "github.com/go-ego/riot"
    "github.com/go-ego/riot/types"
)
var (
    // searcher 是协程安全的
    searcher = riot.Engine{}
)
func main() {
    // 初始化
    searcher.Init(types.EngineOpts{
        Using:             3,
        GseDict: "zh",
        // GseDict: "your gopath"+"/src/github.com/go-ego/riot/data/dict/dictionary.txt",
    })
    defer searcher.Close()
    text := "《复仇者联盟3：无限战争》是全片使用IMAX摄影机拍摄"
    text1 := "在IMAX影院放映时"
    text2 := "全片以上下扩展至IMAX 1.9：1的宽高比来呈现"
    // 将文档加入索引，docId 从1开始
    searcher.Index("1", types.DocData{Content: text})
    searcher.Index("2", types.DocData{Content: text1}, false)
    searcher.Index("3", types.DocData{Content: text2}, true)
    // 等待索引刷新完毕
    searcher.Flush()
    // engine.FlushIndex()
    // 搜索输出格式见 types.SearchResp 结构体
    log.Print(searcher.Search(types.SearchReq{Text:"复仇者"}))
}

是不是很简单！

然后看看一个入门教程，教你用不到200行 Go 代码实现一个微博搜索网站。

使用默认引擎:

package main
import (
    "log"
    "github.com/go-ego/riot"
    "github.com/go-ego/riot/types"
)
var (
    searcher = riot.New("zh")
)
func main() {
    data := types.DocData{Content: `I wonder how, I wonder why
        , I wonder where they are`}
    data1 := types.DocData{Content: "所以, 你好, 再见"}
    data2 := types.DocData{Content: "没有理由"}
    searcher.Index("1", data)
    searcher.Index("2", data1)
    searcher.IndexDoc("3", data2)
    searcher.Flush()
    req := types.SearchReq{Text: "你好"}
    search := searcher.Search(req)
    log.Println("search...", search)
}

Features

Requirements

Go version >= 1.8

Dependencies

Riot uses go module or dep to manage dependencies.

Installation/Update

go get -u github.com/go-ego/riot

Build-tools

go get -u github.com/go-ego/re

re riot

To create a new riot application

$ re riot my-riotapp

re run

To run the application we just created, you can navigate to the application folder and execute:

$ cd my-riotapp && re run

Usage:

Look at an example

package main

import (
	"log"

	"github.com/go-ego/riot"
	"github.com/go-ego/riot/types"
)

var (
	// searcher is coroutine safe
	searcher = riot.Engine{}
)

func main() {
	// Init
	searcher.Init(types.EngineOpts{
		// Using:             4,
		NotUseGse: true,
		})
	defer searcher.Close()

	text := "Google Is Experimenting With Virtual Reality Advertising"
	text1 := `Google accidentally pushed Bluetooth update for Home
	speaker early`
	text2 := `Google is testing another Search results layout with 
	rounded cards, new colors, and the 4 mysterious colored dots again`
	
	// Add the document to the index, docId starts at 1
	searcher.Index("1", types.DocData{Content: text})
	searcher.Index("2", types.DocData{Content: text1}, false)
	searcher.IndexDoc("3", types.DocData{Content: text2}, true)

	// Wait for the index to refresh
	searcher.Flush()
	// engine.FlushIndex()

	// The search output format is found in the types.SearchResp structure
	log.Print(searcher.Search(types.SearchReq{Text:"google testing"}))
}

It is very simple!

Use default engine:

package main

import (
	"log"

	"github.com/go-ego/riot"
	"github.com/go-ego/riot/types"
)

var (
	searcher = riot.New("zh")
)

func main() {
	data := types.DocData{Content: `I wonder how, I wonder why
		, I wonder where they are`}
	data1 := types.DocData{Content: "所以, 你好, 再见"}
	data2 := types.DocData{Content: "没有理由"}

	searcher.Index("1", data)
	searcher.Index("2", data1)
	searcher.Index("3", data2)
	searcher.Flush()

	req := types.SearchReq{Text: "你好"}
	search := searcher.Search(req)
	log.Println("search...", search)
}
