Boolean terms are the connectors between keywords that determine how a search works.  Terms include AND OR and NOT which either broaden or narrow your search. 

Synonyms are use to broaden your search and link keywords with the term OR.  Results will have any of the synonyms.

When separate keywords are needed in the results the term AND is used. This narrows the results to a more targeted outcome.

However if a word keeps appearing that is off topic it can be removed from results by using the term NOT.  It should be used with care as it can easily exclude relevant results.

Here is a link to the Library Guide that demonstrates the effect of working with keywords and explains more advanced Boolean including round brackets, " ", * and ?.
