 Using @{class@libphutil:PhutilEmailAddress} may be helpful in parsing the query.
 
-== Search: Did Update Index ==
-
-The constant for this event is
-`PhabricatorEventType::TYPE_SEARCH_DIDUPDATEINDEX`.
-
-This event is dispatched from the Search application's indexing engine, after
-it indexes a document. It allows you to publish search-like indexes into other
-systems.
-
-Note that this event happens after the update is fully complete: you can not
-prevent or modify the update. Further, the event may fire significantly later
-in real time than the update, as indexing may occur in the background. You
-should use other events if you need guarantees about when the event executes.
-
-Finally, this event may fire more than once for a single update. For example,
-if the search indexes are rebuilt, this event will fire on objects which have
-not actually changed.
-
-So, good use cases for event listeners are:
-
-  - Updating secondary search indexes.
-
-Bad use cases are:
-
-  - Editing the object or document.
-  - Anything with side effects, like sending email.
-
-Data available on this event:
-
-  - `phid` The PHID of the updated object.
-  - `object` The object which was updated (like a @{class:ManiphesTask}).
-  - `document` The @{class:PhabricatorSearchAbstractDocument} which was indexed.
-    This contains an abstract representation of the object, and may be useful
-    in populating secondary indexes because it provides a uniform API.
