Precedence of Search Operators

Boolean and proximity operators have the following precedence:

Highest:      NOT
                 NEAR; DNEAR; XNEAR; YNEAR
                 AND; BEFORE; AFTER; WHEN; SENTENCE; DSENTENCE; PARAGRAPH
Lowest:       OR; WNEAR; EOR

Operators that have the same level of precedence have neither left or right associativity. You can use brackets to bind terms together as appropriate. Proximity operators must have terms on either side, and cannot be adjacent to brackets.
