Is is required to call indexDoc before search

I copied the following code from example and add some options in Riot. It works well if I call Index before query. In reality, all the text data will be read from database, and make indexes if required. But I found if I set variable 'buildIdx' to false and run again, nothing is returned. Does that mean I have to query database and make indexes before query?

package main

import (
    "log"

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

var (
    searcher = riot.Engine{}
)

func main() {
    searcher.Init(types.EngineOpts{
        Using:       3,
        GseDict:     "zh",
        StoreFolder: "./indexes",
        UseStore:    true,
    })
    defer searcher.Close()
    buildIdx := true

    if buildIdx {
        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影复仇院放映时者"

        searcher.Index("你好,世界", types.DocData{Content: text})
        searcher.Index("2", types.DocData{Content: text1}, false)
        searcher.Flush()
    }

    // 搜索输出格式见 types.SearchResp 结构体
    log.Print(searcher.Search(types.SearchReq{Text: "复仇者"}).Docs)
}

Sorry, I finally got it, I need to call searcher.Flush().
