| Search Tips | |
| Adjacency | Multiple words are searched together as one phrase. Example : world health organization |
|---|---|
| Wildcards |
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*, inter**, 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). |
| Grouping | 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. |
