-### Handling events
+### Calling Query methods
+
+Starting with Spring Data REST 1.0.0.M2, the exporter exposes Repository query methods under the special URL path `/repository/search/*`.
+
+To see what query methods are exported, issue a GET request to the entity resource URL and add the segment "search". You'll get back a list of links to the exported search methods.
+
+    curl -v http://localhost:8080/data/person/search
+
+    {
+      "_links" : [ {
+        "rel" : "person.findByName",
+        "href" : "http://localhost:8080/data/person/search/findByName"
+      } ]
+    }
+
+To query for entities using this search method, add a query parameter to the URL. The response will be a list of links to the top-level URL for that resource.
+
+    curl -v http://localhost:8080/data/person/search/findByName?name=John+Doe
+
+    [ {
+      "rel" : "person.Person",
+      "href" : "http://localhost:8080/data/person/1"
+    } ]
+
+To change the URL under which the query method is exported or set the name of the query parameter containing the search term, use the new `@RestResource` annotation.
+
+    @RestResource(path = "people")
+    public interface PersonRepository extends CrudRepository<Person, Long> {
+
+      @RestResource(path = "name", rel = "names")
+      public List<Person> findByName(@Param("name") String name);
+
+    }
+
+This changes the path the PersonRepository is exported under to `/people`, changes the rel of the search URL to `people.names`, changes the path under with the query method is exported to `/name`, and sets the query parameter containing the search term to `name`. To search the Repository using this method, issue a GET request.
+
+    curl -v http://localhost:8080/data/people/search/name?name=John+Doe
