Rationale:

Search box at the top of Wikimedia sites with links to search in sister wikis like in Google. Idea description by Svetlana

Description:

Project Name: SisterSearch

Purpose: For development, we need a MediaWiki instance with a development and debugging environment to minimize platform issues

Wikitech username of requestor: Gryllida

Brief description: Interface to expose inter-project search results on every page, to improve UX, cross-wiki reader and editor engagement. See sketches below.

Special:Search Proposed:

+---------+  +-------+   +-------+    +------------+   <-- NEW tabs for project selection 
| Encyclo |  | Books |   | Media |    | Dictionary |   Tabs would be greyed or coloured if the current page title exists on the sister project.
|          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^+
| Type search query here ....                                                     |
+---------------------------------------------------------------------------------+

Wiki page Proposed:

                                           "Foo" * *  talk prefs watchlist logout

+---------+  +------+   +------+         +---------+
| Read    |  | Talk |   | Edit |         | History |  [\/] [ Type search query here... ]
|          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|  DOG                                                  ^-- NEW Dropdown for project selection
|                                                           Possibly 75% transparency clickable sister project
|   Dog is an animal ...                                    favicon hovering below search box if page title exists.
|   ..........................................................

Or we could try a merged configuration - move search box to the top for both wiki page and special search:

+---------+  +------+   +-------+    +------------+   <-- NEW tabs for project selection
| Encyclo |  | News |   | Media |    | Dictionary |       Tabs would be greyed or coloured if the current page title exists on the sister project.
|          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^+
| Type search query here ....                                                     |
+---------------------------------------------------------------------------------+

+---------+  +------+   +------+         +---------+
| Read    |  | Talk |   | Edit |         | History |    "Foo" * *  [\/]  <-- (Dropdown for talk/prefs/watchlist/logout)
|          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|  DOG
|  
|   Dog is an animal ...
