 Takes no arguments and matches an audio file if and only if no
 attributes are set.
 
-	played_rarely
-
-Takes no arguments and matches all audio files where the number of
-times this audio file was selected is below the average.
-
-	is_set attribute_name
+	is_set <attribute_name>
 
 Takes the name of an attribute and matches iff that attribute is set.
 
-	path_matches pattern
+	path_matches <pattern>
 
 Takes a filename pattern and matches iff the path of the audio file
 matches the pattern.
 
+	artist_matches <pattern>
+	album_matches <pattern>
+	title_matches <pattern>
+	comment_matches <pattern>
+
+Takes an extended regular expression and matches iff the text of the
+corresponding tag of the audio file matches the pattern. If the tag
+is not set, the empty string is matched against the pattern.
+
+	year ~ <num>
+	bitrate ~ <num>
+	frequency ~ <num>
+	channels ~ <num>
+	num_played ~ <num>
+
+Takes a comparator ~ of the set {<, =, <=, >, >=, !=} and a number
+<num>. Matches an audio file iff the condition <val> ~ <num> is
+satisfied where val is the corresponding value of the audio file
+(value of the year tag, bitrate in kbit/s, frequency in Hz, channel
+count, play count).
+
+The year tag is special as its value is undefined if the audio file
+has no year tag or the content of the year tag is not a number. Such
+audio files never match. Another difference is the special treatment
+if the year tag is a two-digit number. In this case either 1900 or
+2000 are added to the tag value depending on whether the number is
+greater than 2000 plus the current year.
