This is why they removed searching for older videos (specific time) and why their search pushes certain algorithmic videos, other older videos when found by direct link are on long term storage and take a while to start loading.
Well the time filters (before/after:date) still seem to work, but for controversial / hot topics, somehow, more recent videos tend to still show up at the top. Try "scandal after:2010 before:2012"..
