 ## Filtering Language Definition
+
 The language definition used in the configuration filters is available [here](https://github.com/antonmedv/expr/blob/586b86b462d22497d442adbc924bfb701db3075d/docs/Language-Definition.md)
 
 ## Filterable Fields
+
 The following torrent fields (along with their types) can be used in the configuration when filtering torrents:
+
 ```go

-	Hash            string  
-	Name            string

 ## Helper Filtering Options
+
 The following helper functions are available for usage while filtering, usage examples are available in the example config above.
+
 ```go
 IsUnregistered() bool // Evaluates to true if torrent is unregistered in the tracker
 HasAllTags(tags ...string) bool // True if torrent has ALL tags specified
 HasAnyTag(tags ...string) bool // True if torrent has at least one tag specified
+HasMissingFiles() bool // True if any of the torrent's files are missing from disk
 Log(n float64) float64 // The natural logarithm function
 ```
 
 ## BypassIgnoreIfUnregistered
+
 If the top level config option `bypassIgnoreIfUnregistered` is set to `true`, unregistered torrents will not be ignored.
