+
+Allows to use error-tolerant search for audio track filtering using *FuzzyWuzzy* algorithm.
+
+The *Minimum tolerance* defines the filtering tolerance between 0 to 100. The *Maximum results* defines the amount of filtered results the filtering should return.
+
+The *Always use error-tolerant search* defines if the *FuzzyWuzzy* algorithm should always be used for filtering, otherwise the algorithm is only used if the normal filtering yields no results.
