Words can be searched as a phrase by enclosing them in double quotation marks. Example : "art therapy"
Words can be searched within a specified range of each other using proximity operators. Use a '~#' after an adjacency search, as above, to specify words within # words of each other, in any order. Example : "art therapy"~5 [finds 'art' and 'therapy' within 5 words of each other]
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 : art* [finds arts, artists, artistic] art** [finds artificial, artillery] gentle*n gentlem?n
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)

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.
