Welcome back to our overview of
the Cochrane Library and
Part 2 of this talk.
With that overview of these
two different databases,
it's time to go over a
more detailed approach to
searching them that will
return more specific results.
This is important for
systematic reviewers as well
as clinicians, just
in your own practice,
if you want to see what
evidence is available for
your specific question more
quickly than manually
filtering and scrolling.

I've put this section
after the introduction to
both the Cochrane Database of
Systematic Reviews and CENTRAL
because the search
is exactly the same
and actually using
the search function
will search both for you
by default, and then
you can use the tabs at
the top that we already
covered to navigate
from which database
you want to screen
and export results.

The quick search is located
at the top right corner of
the main page, entering terms
that you're interested in
and specifying which
fields to search itself
will return anything that
meets those criteria.

Selecting browse just
below the search bar is
another way to manually
sort through the topics.
But this is really just a
quicker way to filter to
a specific topic area,
like can be done on the
main database page.
For example, if we
select eyes and vision,
we get the same page
we would expect
if navigating to the databases
and filtering to this
topic from the left.

Now that is straightforward
and simple,
but more advanced
searching can be done
by selecting the
advanced search button.
Select the search manager to
access embedded shortcuts
to MeSH and keyword terms,
and then add your desired
MeSH and keywords.
We'll go over this more closely.

The Cochrane Library relies on
Medical Subject Headings from
the National Library
of medicine.
These MeSH terms are composed of
controlled vocabulary
of biomedical terms
used to describe the subjects
of a journal article.
As controlled and
structured vocabulary,
they're organized
hierarchically,
so that more specific
terms are grouped together
on larger branches that
are more conceptual
and encompass many
more specific terms.
In addition to MeSH,
it's also important to use
keywords in your search
because they can
account for synonyms,
acronyms, initialisms,
variations in spelling
and other closely
related terms used
interchangeably to describe
the topic, but that
might not have exact matches
in the MeSH dictionary.
To add MeSH terms
to your search,
