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)
}
