There are a couple of quick ways you can
refine your search results in Google Scholar.
You'll find these in the column to the left.
The words in RED denote the options that are
currently selected, which determine the order
of your search results.
Choosing a different refinement will then turn
that option red and all others black.
To narrow your results by publication date,
select one of these options. These three
options - "Since 2012," "Since 2011," and
"Since 2008," mean you will view items that
have been published from that year to the
present, with most recent publications
appearing first in the list.
You can also enter a custom date range by
manually entering the beginning and end
years for your desired range.
Google Scholar will default to showing you
search results sorted by relevance (in
relation to the search you conducted).
You can choose to "Sort by date" if you
prefer to view all your results with the most
recent publications appearing first in the list.
And those are a couple of quick ways you
can refine your search results in Google
