Не нужно создавать сложные условия.

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 

    MenuInflater inflater = getMenuInflater(); 
    // Inflate menu to add items to action bar if it is present. 
    inflater.inflate(R.menu.main, menu); 

    SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); 
    SearchView search = (SearchView) menu.findItem(R.id.action_search).getActionView(); 
    search.setSearchableInfo(manager.getSearchableInfo(getComponentName())); 
    search.setOnQueryTextListener(new SearchView.OnQueryTextListener() { 
     @Override 
     public boolean onQueryTextSubmit(String query) { 
      return false; 
     } 

     @Override 
     public boolean onQueryTextChange(String newText) { 
       PerfromSearch(newText); 
      return false; 
     } 
    }); 
    return true; 
} 

void PerfromSearch(String query) { 

    adapter.filter(query);
