Any Words and All Words searches

An "any words" search is any sequence of text, like a sentence or a question.   In an "any words" search, use quotation marks around phrases, put + (plus) in front of any word or phrase that is required, and - (minus) in front of a word or phrase to exclude it.  Examples:

banana pear "apple pie"

"apple pie" -salad +"ice cream"

An "all words" search request is like an "any words" search except that all of the words in the search request must be present for a document to be retrieved.
