As of today when one uses a search box provided by the InputBox extension the original user query is suffixed by a search keyword prefix:Page :
Example from the english wikipedia manual of style:
pressing Search the MoS will open Special:Search like this (note the prefix:Manual of Style appended to the original user query):
We suggest to change this behavior by showing this instead:
The user query will be left intact but Special:Search will contain an indication that the results are limited to pages whose title starts with XYZ. A small link is added to allow users to reset Special:Search to its defaults, in this case to search in all pages. Note that you should read Wikipedia::Manual of Style instead of Help:Manual of Style this screenshot was taken on a development machine.
This change will only affect Special:Search opened via search boxes made with the InputBox extension using the prefix parameter.
