An all/any words or "natural language" search is any sequence of text, like a sentence or a question. In an "all/any words" search, use quotation marks around phrases. Optionally, you can also put + in front of any word or phrase that is required, and - in front of a word or phrase to exclude it. Examples:

banana pear "apple pie"
"apple pie" -salad +"ice cream"

A boolean search request consists of a group of words or phrases, linked by connectors such as AND and OR that indicate the relationship between them. Examples:

Search Request	Explanation
apple and pear	both words must be present.
apple or pear	either word can be present.
apple w/5 pear	apple must occur within 5 words of pear.
apple not w/5 pear	apple must not occur within 5 words of pear.
apple and not pear	only apple must be present.
apple w/5 xfirstword	apple must occur in the first five words.
apple w/5 xlastword	apple must occur in the last five words.

If you use more than one connector, you should use parentheses to indicate precisely what you want to search for. For example, apple and pear or orange juice could mean (apple and pear) or orange, or it could mean apple and (pear or orange).

Noise words, such as if and the, are ignored in searches.
