+ * Provides a "matches" operator used for tagging rules.
+ *
+ * It asserts that a given pattern is contained in a subject, in a
+ * case-insensitive way.
+ *
+ * This operator will be used to compile tagging rules in DQL, usable
+ * by Doctrine ORM.
+ * It's registered in RulerZ using a service (wallabag.operator.doctrine.matches);
