To enter a query into the Search Page, just type in a few descriptive words and hit the 'enter' key (or click on the Search button) for a list of relevant web pages.

For best results, it's important to choose your keywords wisely. Keep these tips in mind:
Try the obvious first. If you're looking for information on Picasso, enter "Picasso" rather than "painters".
Use words likely to appear on a site with the information you want. "Luxury hotel Pittsburgh" gets better results than "really nice places to spend the night in Pittsburgh".
Make keywords as specific as possible. "Antique lead soldiers" gets more relevant results than "old metal toys".

By default, if the input consists of more than one word or group of letters separated by a space, and includes neither an operator (OR, AND, NOT) nor quotation marks, the search-engine sets by default an "OR" in between the words.

Keep in mind that the order in which the operators are typed will affect the search results. The "AND" and the "NOT" operators are preformed before the "OR" operators.

All letters, regardless of how you type them, will be understood as lower case. For example, searches for "george washington", "George Washington", and "gEoRgE wAsHiNgToN" will all return the same results.

Means that the word (search string) following this operator has to be contained in the full text of the paper.

Means that the word (search string) following this operator may alternatively be contained in the full text of the paper.

Means that the word (search string) following this operator must not be contained in the full text of the paper.

Quotation Marks are used to embrace a group of words which should be treated as one expression.

Examples:

Searches for all pages whose full text contains either the word "Jefferson" or the word "Mellon"

Searches for all pages whose full text contains both the word "Jefferson" and the word "Mellon"

Searches for pages which contain the word "Jefferson" but not the word "Mellon"

Searches for all pages whose full text contains the words "Jefferson School" in exactly this word order, i.e. with a blank in between
