If many users are customizing their search settings, we're doing something
(In reply to Quiddity from bug 52817 comment #40)
Searching for help documentation is HELL unless we add the Wikipedia: ,
Help: , and Template: namespaces to our default search. For the first few
years as a new editor, I was constantly searching those namespaces for tools
and guides. (Note that the Template: and Category: namespaces aren't
included in the "Help and Project pages" output)
That tab was removed: https://gerrit.wikimedia.org/r/#/c/132965/1 Which makes sense for most MediaWiki installations but not for Wikimedia projects editors.
Until bug 22774 is fixed or some hook is found to add the tab again on Wikimedia projects, I think we must add Help to $wgNamespacesToBeSearchedDefault on all wikis: results from it will mostly be what users expect, when they come up.
Personally I recommend against Project, or even worse Template, because on many wikis they contain an entire ghost project, often with article-like titles and content. See for instance some Wikipedias which have almost a *million* pages in either, extreme right of https://stats.wikimedia.org/EN/TablesCurrentStatusVerbose.htm
