+breaking:
+  title: Unquoted index patterns do not allow `(` and `)` characters
+  area: ES|QL
+  details: >-
+    Previously, ES|QL accepted unquoted index patterns containing brackets, such as `FROM index(1) | ENRICH policy(2)`.
+
+    This query syntax is no longer valid because it could conflict with subquery syntax, where brackets are used as delimiters.
+
+    Brackets are now only allowed in quoted index patterns. For example: `FROM "index(1)" | ENRICH "policy(2)"`.
+  impact: "This affects existing queries containing brackets in index or policy names, i.e. in FROM, ENRICH, and LOOKUP JOIN commands."
