Listing YouTube videos using API with RxJava

Question

I am new to RxJava and have the following code which I use to search YouTube videos via the API and ultimately display them in a list.

private fun showYouTubeSearchView() {
    val youtubeSearchView = viewFactory.getYouTubeSearchView(null)
    val contentView = youtubeSearchView.rootView

    youtubeSearchView.subscribeSearchEvent()
        .subscribeOn(Schedulers.io())
        .observeOn(Schedulers.io())
        .switchMap { searchTerm ->
            searchYouTubeUseCase.searchYouTube(searchTerm)
                .flatMapIterable { youTubeSearchResults ->
                    youTubeSearchResults.items
                }
                .flatMap { item ->
                    getVideoStatisticsUseCase.getViewCount(item.id.videoId)
                        .flatMap { viewCount ->
                            Observable.just(
                                YouTubeListItemModel(
                                    item,
                                    viewCount
                                )
                            )
                        }
                }
                .toList()
                .toObservable()
        }
        .observeOn(AndroidSchedulers.mainThread())
        .flatMap { youTubeListItemModels ->
            youtubeSearchView.showSearchItems(youTubeListItemModels)
            youtubeSearchView.subscribeItemClicked()
        }
        .subscribe(
            { youTubeListItemModel ->
                showCreateVideoClipView(youTubeListItemModel)
            },
            { t ->
                Snackbar.make(contentView, "Error", Snackbar.LENGTH_LONG).show()
                Log.e(TAG, "error", t)
            }
        )

    setContentView(contentView)
}

You will notice a second API call is required to get the view count for each item in the list.

I hope the code is relatively understandable as-is. I feel as though the doubly nested switchMap/flatMap/flatMap is probably indicative of poor design. Is there a better way of accomplishing the same thing?
