Advanced search permits precise queries to be made. When more than one field is entered all fields must match.
The default mode is wildcard, this means you can use ? to match any single character, or * to match any number of characters. If you do not use * or ? a literal whole word match is required.
Alternatively you can use fuzzy mode. In fuzzy mode ? and * have no special meaning. In fuzzy mode non-exact matches will be returned.
Certain fields such as the language field are always treated literally and wildcards and fuzzy mode have no effect.
