问题 I finally figured out how to implement pg_search's multisearch feature. But I'm having trouble making a usable search page that displays links back to the appropriate nested pages.

I can call excerpt(content, @query) to get exactly what I want when @query is only one word, but excerpt() only handles exact matches, so if: @query = 'car
