You still use the Boolean operators written in English when searching for information in Spanish.
Use OR to broaden your search.
For example, if you search jubilación OR pensión, you will find articles that include either term.
Use AND to narrow your search.
For example, if you search jubilación AND México, you will only find articles that include both terms.
Use AND and OR together.
For example, if you search (jubilación OR pensión) AND México, you will find articles that include both retirement and Mexico, as well as articles that include both pension and Mexico.
Use quotation marks to search for a phrase (two words or more).
Use a truncation symbol (the asterisk * is the most common) to look for different word endings.
