sunspot/sunspot — Issue #161: calling the DSL full_text method doesn't return the filter itself

without which I cannot exclude it from my facet multiselect call similar to what is shown in the following excerpt from http://outoftime.github.com/ (only with the 'full_text' filter instead of the 'with' filter)

Sunspot.search(Post) do
keywords('some keywords')
with(:blog_id, 1)
category_filter = with(:category_id, 3)
facet(:category_id, :exclude => category_filter)
end
