In a standard search, results containing all the search terms are shown. By inserting the word OR between the search terms, you can widen the search to include hits with only part of the terms. Wildcard searches are also possible if you enter an asterisk (*) to allow for random letter sequences and a question mark (?) to search for an individual letter. If you enter the tilde symbol (~) at the end of an individual word, you can do a fuzzy search.
