Words may be right-hand truncated using an asterisk ('*') in place of other characters. The '*' wildcard may also be embedded in a search string. You may also use '?' to replace a single character anywhere within a word:
environment* polic*, wom?n
Use "and" or "or" to specify multiple words in any field, any order. Use "and not" to exclude words:
romans and commentaries
(china or japan) and (buddhism and not hinduism)
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.
