+
+Updated the search configuration class to use the static `fromConfig`-based constructor for the `DefaultCatalogCollator`.
+
+To apply this change to an existing app, replace the following line in `search.ts`:
+
+```diff
+-collator: new DefaultCatalogCollator({ discovery })
++collator: DefaultCatalogCollator.fromConfig(config, { discovery })
+```
+
+The `config` parameter was not needed before, so make sure you also add that in the signature of `createPlugin`
+in `search.ts`:
+
+```diff
+export default async function createPlugin({
+  logger,
+  discovery,
++  config,
+}: PluginEnvironment) {
+```
