| Keyword and Phrase Searching |
Multiple words not in quotes are searched first as a phrase. Results are shown with any phrase matches and then with the words searched individually but "anded" together. Example : world health organization is searched both as a phrase and also as if you had used AND between each word, as world AND health AND organization. To search only as a phrase or if the phrase includes boolean operators (AND, OR, NEAR, AND NOT, BEFORE, AFTER, WITHIN) your search MUST be enclosed in quotes. Example : "black and white". |
|---|---|
| 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*, 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 |
| 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. |
