+# ADR 0003: Search via ILIKE instead of pg_trgm
+
+- Status: accepted
+- Date: 2026-09
+
+## Context
+Message search must find substring matches across a user's conversations.
+pg_trgm + GIN gives indexed trigram search, but the extension is not
+installed on the target system and cannot be created by a non-superuser role
+(and adding it to the Docker image is an OS-level dependency).
+
+## Decision
+Search with `body ILIKE '%term%'` restricted to the user's conversations,
+ordered by message id descending with a limit.
+
+## Consequences
+- No extension or superuser requirement; works on any PostgreSQL install.
+- Sequential scan is instant for thousands of messages (family scale).
+- Scaling path documented: `CREATE EXTENSION pg_trgm` + GIN index with
+  `gin_trgm_ops`, keeping the same SQL semantics.
