AND is the default operator. Entering multiple words without an operator will match pages that contain ALL of those words.

The OR operator allows matching pages that contain either word.

You can use the NOT operator to exclude certain words from the search results.

Exact strings can be matched by placing them inside double quotes ("). Only whole word matches will be considered for words placed within double quotes.

You can change the order of evaluation of the search string by using () brackets. Expressions inside brackets will be evaluated first.

All search words and operators are not case sensitive. Matches will be found in the page title, keywords, description and body text.

jury duty	contain the word jury and the word duty (equivalent to "jury AND duty")
