[00:00:10.153]The term clusters tool generates
a visual representation of your results
by topic and subtopic
based on an analysis of frequently occurring
and related terms.
There are two ways to visualize your results.
In the wheel view, terms that occur most frequently
appear in the inner ring.
More specific terms appear in the outer ring.
The darker and redder a term appears,
the more popular that term is.
The lighter and greener a term appears,
the less popular that term is.
Use term clusters if you're having trouble coming up
with a research topic,
when you have an idea for a topic
and want to investigate related topics,
or when you want to narrow your search results
because the search returns a large number of results.
