Tabs below an ion-header-bar

Hey guys,
I need a header-bar with a search input-field and tabs below that bar.
With my code, there’s whitespace between header-bar and the tabs.

Here’s my code:
index.html

<ion-header-bar class="bar item-input-inset bar-dark">
  <label class="item-input-wrapper">
    <i class="icon ion-search placeholder-icon"></i>
    <input type="search" placeholder="Was suchst">
  </label>
</ion-header-bar>

<ion-nav-view></ion-nav-view>

If I remove the item-input-inset, everything is fine. But I need it… maybe I’m using it the wrong way. Anyone knows how to fix it?

I managed to move the bar to the top, but now there’s the whitespace between tabs and content…

ionic.app.scss

.tab-nav.tabs {
  top: 0px;
}
