To create a new riot application
$ re riot my-riotapp
To run the application we just created, you can navigate to the application folder and execute:
$ cd my-riotapp && re run
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!
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)
}
