Function of the "AND" operator

The boolean operator "AND" allows you to search for two correlated terms or expressions.

The "AND" operator is one of the most commonly used operators in any documentary research. It
will enable you to gather information concerning both terms without being polluted by news only
relevant to one of the terms individually. These articles will be excluded by Geotrend in order to
only present relevant information. This operator helps to specify an informational search by
limiting the documents brought up.

The AI interprets the space as an "AND" when consulting search engines. So there is no need to materialize it. However it will not have any impact if you materialize it.
