Unable to get input value in Razor Page – Html

Do you know what to put at the asp-route-word, I am not able to find it. This is my code:

<form class="d-flex" method="get">
   <input class="form-control me-sm-2" type="search" placeholder="Search" id="searchWord" />
   <button class="btn btn-secondary my-2 my-sm-0" type="submit" asp-controller="Word" asp-action="Index" asp-route-word="???">
                        Rechercher
   </button> </form>

Here is the function in my controller:

public IActionResult Index(string? word)
    {
        if (word == null)
        {
            IEnumerable<Word> objWordList = _db.Words;
            return View(objWordList);
        }
        else
        {
            IEnumerable<Word> objWordList = _db.Words.ToArray().Where(w => word.StartsWith(w.NewWord));
            return View(objWordList);
        }
        
    }

So do you know how to get input text in order to pass it to my controller? I always get word null.
Thanks!

    You have to give the name and value property to your button:

    <button name="word" value="Rechercher" class="btn btn-secondary my-2 my-sm-0" type="submit" asp-controller="Word" asp-action="Index">
   Rechercher
</button>

    And your Controller method will be the same.

    OR

    You can use Request.Form from the name tag to access the form variables:

    public IActionResult Index()
{

    if (Request.Form["word"] == null)
    {
        IEnumerable<Word> objWordList = _db.Words;
        return View(objWordList);
    }
    else
    {
        IEnumerable<Word> objWordList = _db.Words.ToArray().Where(w => word.StartsWith(w.NewWord));
        return View(objWordList);
    }   
}

    <input name="word" class="form-control me-sm-2" type="search" placeholder="Search" id="searchWord" />
    <button  class="btn btn-secondary my-2 my-sm-0" type="submit" asp-controller="Word" asp-action="Index">

</form>
