you can use the d-flex function from bootstrap like this:
<div class="input-group d-flex justify-content-end">
<text class="font-weight-bold float-left" >Lotti</text>
<div class="input-group-append float-right">
<input type="text" class="m-0 form-control form-control-sm" style="max-width: 150px;height:25px" @bind="testoRicerca" @bind:event="oninput" @onkeypress="CercaLotto" />
<button class="border-0 bg-filter m-0" title="Cerca lotto" @onclick="TrovaLotto"><i class="fas fa-search fa-lg"></i></button>
<button class="@buttonPoszioniLottoClass" title="Posizioni lotto" @onclick="ShowPosizioniLotto"><i class="fas fa-crosshairs fa-lg"></i></button>
<button class="border-0 bg-transparent m-0" title="Note di entrata lotto" @onclick="ShowNoteEntrataLotto"><i class="far fa-clipboard fa-lg"></i></button>
</div>
