Adjacency Multiple words in quotes are searched together as one phrase.
Example : "world health organization"
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)
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
Proximity Operators Use ~ to search for two words that occur within a specified number of words of each other in a record. You must enclose the keywords in quotes and place the ~ operator after the keywords to use this feature. Note that wildcards are not supported with the proximity operator.
Example : "&fractal geometry"~5 (the two words must appear within three words of one another (meaning that up to three words may separate the keywords)
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. Results can also be sorted within the group by date or title. To get an ungrouped result set, use boolean operators to form a complex query.
Modify You can also modify your search using the Modify Search button. Add or delete fields, select material types and choose specific dates or other options from the pulldown Limit Your Search menu.
