it does work, use it here to find out why you might think the same, it has been asked many times. (surely related to how fulltext search on mysql works)
Looks like the issue is when using the search form, spaces are not turned into + within the URI, unlike this site which converts spaces to + on search.

some thing
and it did not show... a search for:
some+thing
however did show the expected results.
Also tried:
"some thing"
which as the first, returned no results either. But "some+thing" did.
Question is; why.
