Force action Bar show search view

I am able to expand search view by action like this

<item android:id="@+id/menu_search"
          android:title="Search"
          android:showAsAction="never|collapseActionView"
          android:actionViewClass="android.widget.SearchView" />

But i have a 3-tab activity and i'd like to SearchView be always expanded How may I do that?
