By default, this search engine looks for any word supplied. Only words of 4 or more letters are used.
To search for an exact phrase, enclose the phrase in quotes. This doesn't work well with Japanese names.
To only get entries which contain a specific keyword, prefix it with "+".
To only get entries that don't contain a specific keyword, use the "-" operator.
To match partial keywords, add the "*" (asterisk) symbol at the end.
