FOCUS
Screen 1 of 2
FOCUS
is a completely separate decision from EXPLODE.
FOCUS will restrict your search to those citations in which the subject heading (MeSH term) is considered
the focus, main topic, emphasis, or major point of the articles.
There are two ways to approach
the decision about whether to FOCUS your search:
- If
there is a lot of literature on your topic click on Focus.
Using the Focus command will retrieve fewer articles,
but these will emphasize the subject rather than simply mention it as a peripheral or secondary topic.
- To begin
with a broad search strategy or comprehensive search do not Focus.
Important
Note: Never Focus country names or geographic regions.
Avoid Focusing if your topic is new, rare, or does not have a lot of literature
to represent it.
