List important keywords relevant to your search topic. For example, "feline cat kitty tiger". This will return a list of all documents containing any of these four words. To narrow your search, use Boolean operators.

Finds only documents containing all of the specific words or phrases. For example, "feline & cat" finds documents which contain both the word "feline" and the word "cat". |
|
|
|
Finds documents containing at least one of the specified words or phrases. For example, "feline | cat" finds documents containing either "feline" or "cat". The found documents could contain both, but do not have to. |
|
|
|
Excludes documents containing the specific word or phrase. For example, "feline ! cat" finds documents containing "feline" but not containing "cat". As with the & and | operators, ! must appear between two terms. |

Used to group portions of boolean queries together for more complicated queries. For example, "feline & [cat | kitty] ! tiger" finds documents containing "feline" and either "cat" or "kitty" but not "tiger". (If a document contains "tiger," it will not be returned even if it meets the other criteria.) |
