The search engine also supports special characters and parameters to extend the power
of searches and allow users to make their search strings more specific.
At the search results page， Special:Search， Advanced
dialog， a search can specify any number of namespaces， and logged-in users can set their default search
domain there by clicking "Remember selection for future searches".
This section is about search parameters. Parameters function as
name filters， each followed by the search term it operates on. The search box will navigate directly to a given page name upon an exact
match. The search results highlight occurrences in both the title and page content.
The search results page can open in a new
tab. You can just drag items on the page the name up to the web browser search box while on any web site， even in the
lower sections of a Wikipedia page， where no search box
is immediately available.
