title: How would you do RandomizedSearchCV with VotingClassifier for Sklearn?
body: <p>I'm trying to tune my voting classifier. I wanted to use randomized search in Sklearn. However how could you set parameter lists for my voting classifier since I currently use two algorithms (different tree algorithms)? 
  Do I have to separately run randomized search and combine them together in voting classifier later?</p>
  
  <p>Could someone help? Code examples would be highly appreciated :)</p>
  
  <p>Thanks!</p>
