On my MediaWiki 1.4.0 system, I notice that a search for "plan" does not
match text or titles with the word "plans" (among other similar mismatches).
Can I change this behavior (such that "plan" will match "plans") in my
1.4.0 system? In not, do later MediaWiki versions address this and/or
might future MediaWiki version support this feature? Is there an
advanced-search feature available in 1.4.0 or later/future versions?
