Search Tips

Multiple words are searched together as one phrase.
Example: world health organization
Words may be right-hand truncated using an asterisk. '*' for 1-5 characters, '**' for open-ended truncation, '?' to replace a single character anywhere within a word.
Examples: environment* polic*, comput**, wom?n
Boolean Operators
Use "and" or "or" to specify multiple words in any field, any order. Use "and not" to exclude words.
Example: stocks and bonds
Example: (alaska or canada) and (adventure and not vacation)
Proximity Operators
Use "near" to specify words close to each other, in any order.
Example: california near university
Field limits
A field limit causes the system to search only the specified field for the specified word(s).
Keyword search results are usually grouped by relevance to bring the most likely titles to the top of the list. Each group represents a similar level of relevance and results are sorted within the group by date or title. To get an ungrouped result set, use boolean operators to form a complex query.
