没有本机引导解决方案。您可以使用自定义代码执行此操作。

.custom-search {
  position: relative;
  width: 300px;
}
.custom-search-input {
  width: 100%;
  border: 1px solid #ccc;
  border-radius: 100px;
  padding: 10px 100px 10px 20px; 
  line-height: 1;
  box-sizing: border-box;
  outline: none;
}
.custom-search-botton {
  position: absolute;
  right: 3px; 
  top: 3px;
  bottom: 3px;
  border: 0;
  background: #d1095e;
  color: #fff;
  outline: none;
  margin: 0;
  padding: 0 10px;
  border-radius: 100px;
  z-index: 2;
}
<div class="custom-search">
  <input type="text" class="custom-search-input" placeholder="Enter your email">
  <button class="custom-search-botton" type="submit">Subscribe</button>  
</div>

根据引导程序样式，使用引导程序混合解决方案。

   .custom-search {
      position: relative;
    }
    .custom-search-input {
      width: 100%;
      padding-right: 100px !important; 
      box-sizing: border-box;
    }
    .custom-search-botton {
      position: absolute;
      right: 3px; 
      top: 3px;
      bottom: 3px;
      line-height: 1 !important;
      z-index: 4;
    }

 </div>

您不能仅使用引导程序将按钮放在输入字段内，但可以使用自定义CSS将按钮移动到输入字段内。我为您创建了一个小示例（我使用了引导程序4）：

input[type="text"] {
    width: 200px;
    height: 50px;
    padding-right: 50px;
}

.example {
    margin: 5px -90px 5px;
    height: 40px;
    width: 80px;
    z-index: 100;
}

.test-div {
    width: 200px;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet" />
<div class="test-div">
    <div class="input-group">
       <input type="text" class="form-control" placeholder="Search for...">
       <button class="btn btn-outline-secondary example" type="button">Button</button>
    </div>
</div>
