+// ScriptLanguage represents the different scripting languages supported by Elasticsearch.
+//
+// ScriptLanguage is a string type used to specify the language of a script in Elasticsearch queries.
+// It defines various options for scripting, allowing users to perform advanced calculations,
+// filtering, and custom scoring within search queries.
+//
+// Example usage:
+//
+//	var lang ScriptLanguage = Painless
+//
+//	// Use lang in a script configuration
+//
+// Constants:
+//   - Painless: The default and most efficient scripting language in Elasticsearch.
+//   - Expression: A lightweight, fast scripting language for numeric calculations.
+//   - Mustache: A template-based scripting language used for rendering responses.
+//   - Java: A scripting option that allows Java code execution within queries.
