Keyword	Example	Description
any terms	`pineal pituitary`	Searches for documents matching all terms. The example matches documents that have both the term pineal and the term pituitary.
`AND`	`pineal AND pituitary`	Combines the terms on either side with an `AND` . This example is equivalent to the previous example, as `AND` is the default way to combine terms.
`OR`	`pineal OR pituitary`	Combines the terms on either side with an `OR` . The example matches documents that have at least one of either of the terms pineal or pituitary.
`" "`	`"yoga of awareness"`	Anything within the double-quote marks is treated as a phrase. The example matches documents having the phrase `"yoga of awareness"` (without the double-quote marks).
`NEAR`	`pineal NEAR pituitary`	Matches terms on either side of the `NEAR` where they are within 10 terms of each other. The example matches documents where `pineal` is within 10 terms of `pituitary` . If you add a `/` followed by a number to the keyword, then it uses the number to specify the number of terms for the distance. For example, `pineal NEAR/2 pituitary` matches `pineal` within 2 terms of `pituitary` .
`( )`	`(pineal OR pituitary) thymus`	Indicates grouping. The example matches documents that have at least one of the terms pineal or pituitary, and also have the term thymus.
`-`	`pineal -pituitary`	Indicates a NOT query. The example matches documents matching pineal but not matching pituitary.
