Use the following Boolean operators to specify the relationship between the terms in your search:

and all search terms in same document, e.g. customary and right
or either or both search terms in the same document, e.g. customary or ordinary
/n/ Terms within n terms of each other where n is a number, e.g. statutory right /10/ wages
near Terms within 50 words of each other, e.g. right near recreation
not to exclude documents with a specific term, e.g. customary not statutory
( ) If you use multiple operators in your search, use parentheses to resolve any ambiguity.

Terms placed within parentheses are processed as a unit and are processed before the terms and/or operators outside the parentheses, e.g.

(terminat* or dismiss*) and statutory right /10/ wages
requires the either the word root terminat* or dismiss* to be in the same document with the word wages or wage within ten or fewer words of the phrase statutory right

(patient or parent) /3/ best /3/ interest /3/
requires either the word patient or parent to be within three or fewer words of best with three or fewer words of interest.

(customary or traditional) near (recreation* /5/ right)
searches for the word customary or traditional within 50 words or fewer of the word root recreation* within five words or fewer of the word right.

(Public /10/ recreation*) /5/ (purpose or use)
the word public within ten words or fewer of the word root recreation* must be within five words or fewer of the word purpose or the word use.
