Instructions

The OR operator ("|") can be used to search for documents about either cats or kitties:

cats | kitties

The AND operator can be used to search for documents about both space and exploration. The AND operator is used by default, but can be made explicit with the "&" symbol:

space & exploration

The NOT operator ("-" or "!") can be used to exclude documents about landscapes when searching for Vista:

Vista -landscape

You can surround phrases in quotes, for instance to search for famous quotations:

shakespeare "to be or not to be"

You can use the proximity operator ("~") to search for a group of words within a certain distance of each other. For instance, to search for the words "Saturn", "rings", and "size", all within a span of less than 10 words:

"Saturn rings size"~10

The quorum operator ("/") can be used to do fuzzy matching. If you would like to find documents that have at least three of the five words "college", "university", "learning", "study", "library":

"college university learning study library"/3

OR operator precedence is higher than AND, so "looking for cat | dog | mouse" means "looking for ( cat | dog | mouse )" and not "(looking for cat) | dog | mouse".

Important note on parentheses: You can use parentheses to override the normal precedence order; however, nested parentheses are not allowed. The NOT operator cannot be used within parentheses, only at the top level.
