Simply enter one or more keywords and the search engine will return all pages that contain either all keywords (AND query) or at least one keyword (OR query).  Select "match all words" for an AND query, or select "match any word" for an OR query.

By default, the search engine searches for exact keywords only. This means that a search for gov will not return pages containing the word government. However, if you want to search for all words that begin with gov, you can add an asterisk (*) after the keyword (gov* instead of gov).  You can also put the wildcard in front of a keyword or in the middle of a keyword.

Sometimes you only need results that include an exact phrase.

E.g. you want to search for, signer of the Declaration of Independence, Benjamin Rush's comments on the importance of the Bible as a school book.  Searching for Bible as a school book could also return an event at a local school where the topic is "the importance of the Bible as the guide to a relationship with God through Jesus - as well as the guide for integrity and sound public policy," followed by a buffet dinner.

To narrow your results, simply put quotation marks around your search term ("Bible as a school book" instead of Bible as a school book) and the search engine will only return pages that contain the exact phrase.

This feature is particularly useful when you are searching for multiple keywords (OR query) but still want to ensure that a page contains a certain keyword. To force a keyword, put a plus (+) in front of it (without space).

E.g. if you want to know about attacks on Christian religious liberty, you are basically looking for pages that contain either the word Christian or religious and the word liberty. Therefore your search term should be Christian religious +liberty.

To exclude a keyword, put a minus (-) in front of it. Thus, pages containing this keyword will not be returned.
