Replacement for setTypes(list of types) in 7.8 version - can we pass multiple indices to SearchRequest

In 5.5.2 version we had a search query as shown below which uses settypes array(basically list of types).
SearchRequestBuilder searchBuilder = client.prepareSearch(index).setTypes((String) types.toArray(new String[types.size()])).setFrom(startIndex).setSize(size);
In 7.8 we are planning to move to typeless. What should I replace setTypes array with. We are replacing each type with an index now. So, Should I loop the search request object inside the list of indices. Can we pass multiple indices to Searchrequest like how we pass multiple types. Please let me know how shld I proceed in this case

Ok found that SearchRequest takes multiple indices trying that right now.
