The tweets gained by query standard operators is much less than expected

[Ziyu0118]

I attempted to search for tweets using standard operators with "river pollution" as my keyword. My goal was to find tweets related to this topic and discover the location of the authors. My code is shown as:

package main

import ( "context" "fmt" twitterscraper "github.com/n0madic/twitter-scraper" "github.com/xuri/excelize/v2" "strconv" "time" )

func main() { scraper := twitterscraper.New() err := scraper.Login("XXX", "XXX") if err != nil { panic(err) }

f:=excelize.NewFile()
sum := 2

f.SetCellValue("Sheet1","A1","UserName")
f.SetCellValue("Sheet1","B1","UserID")
f.SetCellValue("Sheet1","C1","Text")
f.SetCellValue("Sheet1","D1","Views")
f.SetCellValue("Sheet1","E1","Likes")
f.SetCellValue("Sheet1","F1","Retweets")
f.SetCellValue("Sheet1","G1","Place")
f.SetCellValue("Sheet1","H1","Time")
f.SetCellValue("Sheet1","I1","TimeStamp")
f.SetCellValue("Sheet1","J1","Hashtags")
f.SetCellValue("Sheet1","K1","Replies")
f.SetCellValue("Sheet1","L1","ID")
f.SetCellValue("Sheet1","M1","Mentions")
f.SetCellValue("Sheet1","N1","Names")
f.SetCellValue("Sheet1","O1","HTML")

for tweet := range scraper.SearchTweets(context.Background(),
    "river pollution -filter:en", 1000) {
    if tweet.Error != nil {
        panic(tweet.Error)
    }
    //fmt.Println(tweet.Text)
    fmt.Println(sum)
    sumindex := strconv.Itoa(sum)
    sum_A:="A"
    sum_A += sumindex
    sum_B:="B"
    sum_B += sumindex
    sum_C:="C"
    sum_C += sumindex
    sum_D:="D"
    sum_D += sumindex
    sum_E:="E"
    sum_E += sumindex
    sum_F:="F"
    sum_F += sumindex
    sum_G:="G"
    sum_G += sumindex
    sum_H:="H"
    sum_H += sumindex
    sum_I:="I"
    sum_I += sumindex
    sum_J:="J"
    sum_J += sumindex
    sum_K:="K"
    sum_K += sumindex
    sum_L:="L"
    sum_L += sumindex
    sum_M:="M"
    sum_M += sumindex
    sum_N:="N"
    sum_N += sumindex
    sum_O:="O"
    sum_O += sumindex
    
    t:=tweet.Timestamp
    
    views:=strconv.Itoa(tweet.Views)
    likes:=strconv.Itoa(tweet.Likes)
    retweets:=strconv.Itoa(tweet.Retweets)
    //timei:=time.Unix(t,0).Format("2023-08-01 03:15:36 +0000 +0000")
    timei:=tweet.TimeParsed.Format("2006-01-02 15:04:05")
    
    
    //place:=strconv.Itoa(tweet.Place)
    //fmt.Println(sum_A)
    //fmt.Println(sum_B)
    //fmt.Println(sum_C)
    //fmt.Println(tweet.TimeParsed.Format("2006-01-02 15:04:05"))
    //fmt.Println(tweet.Hashtags)
    f.SetCellValue("Sheet1",sum_A,tweet.Username)
    f.SetCellValue("Sheet1",sum_B,tweet.UserID)
    f.SetCellValue("Sheet1",sum_C,tweet.Text)
    f.SetCellValue("Sheet1",sum_D,views)
    f.SetCellValue("Sheet1",sum_E,likes)
    f.SetCellValue("Sheet1",sum_F,retweets)
    f.SetCellValue("Sheet1",sum_G,tweet.Place)
    f.SetCellValue("Sheet1",sum_H,timei)
    f.SetCellValue("Sheet1",sum_I,t)
    f.SetCellValue("Sheet1",sum_J,tweet.Hashtags)
    f.SetCellValue("Sheet1",sum_K,tweet.Replies)
    f.SetCellValue("Sheet1",sum_L,tweet.ID)
    f.SetCellValue("Sheet1",sum_M,tweet.Mentions)
    f.SetCellValue("Sheet1",sum_N,tweet.Name)
    f.SetCellValue("Sheet1",sum_O,tweet.HTML)
    
    
    sum+=1
    
    time.Sleep(1*time.Second)
    
}

err2:=f.SaveAs("Test4.xlsx")
if err2 != nil{
    fmt.Println(err)       
}

}

The problem is that the total tweets I gained is only 240, which is much less than the expectation. I think there should be something wrong with my code. If possible, would you mind you guys taking a sight to see what I can do about it? Thanks in advance!
