“Unlike Google Scholar, PubMed provides indexed content
that is directly relevant to physicians, including clinical
controlled vocabulary (MeSH [medical subject headings]),
search limits (such as limiting articles by age or study type),
and access to discipline-specific and methods search filters”.
“Google Scholar retrieved three times as many relevant
articles with free full-text access compared with PubMed”.
22. A systematic review is a high-level overview of primary
research on a focused question that identifies, selects,
synthesizes, and appraises all high quality research
evidence relevant to that question. It is very different from
a literature review, which provides an overview of a topic.
A clinical study/clinical query is original research which
indicates a specific therapy, diagnosis, etiology, prognosis.

Increasing the comprehensiveness of a search will reduce its precision and will retrieve
more non-relevant results.
