+# Kibana GlobalSearch plugin
+
+The GlobalSearch plugin provides an easy way to search for various objects, such as applications
+or dashboards from the Kibana instance, from both server and client-side plugins
+
+## Consuming the globalSearch API
+
+```ts
+startDeps.globalSearch.find('some term').subscribe({
+  next: ({ results }) => {
+    addNewResultsToList(results);
+  },
+  error: () => {},
+  complete: () => {
+    showAsyncSearchIndicator(false);
+  }
+});
+```
+
+## Registering custom result providers
+
+The GlobalSearch API allows to extend provided results by registering your own provider.
+
+```ts
+setupDeps.globalSearch.registerResultProvider({
+  id: 'my_provider',
+  find: (term, options, context) => {
+    const resultPromise = myService.search(term, context.core.savedObjects.client);
+    return from(resultPromise).pipe(takeUntil(options.aborted$);
+  },
+});
+```
+
+## Known limitations
+
+### Client-side registered providers
+
+Results from providers registered from the client-side `registerResultProvider` API will
+not be available when performing a search from the server-side. For this reason, prefer
+registering providers using the server-side API when possible.
+
+Refer to the [RFC](rfcs/text/0011_global_search.md#result_provider_registration) for more details
+
+### Search completion cause
+
+There is currently no way to identify `globalSearch.find` observable completion cause:
+searches completing because all providers returned all their results and searches
+completing because the consumer aborted the search using the `aborted$` option or because
+the internal timout period has been reaches will both complete the same way.
