 Parameter | Required/Optional | Data type | Description
 :--- | :--- | :--- | :---

-`flags` | Optional | String | [Java regex flags](https://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html#field.summary) that modify the behavior of the regular expression.
-`lowercase` | Optional | Boolean | Convert tokens to lower case. Default is `true`.
-`stopwords` | Optional | String or list of strings | Custom list or predefined list of stop words. Default is `_none_`.
-`stopwords_path` | Optional | String | Path (absolute or relative to config directory) to the list of stop words.
+`flags` | Optional | String | A string containing pipe-separated [Java regex flags](https://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html#field.summary) that modify the behavior of the regular expression.
+`lowercase` | Optional | Boolean | Whether to convert tokens to lowercase. Default is `true`.
+`stopwords` | Optional | String or list of strings | A string specifying a predefined list of stopwords (such as `_english_`) or an array specifying a custom list of stopwords. Default is `_none_`.
