Search extension broken in edge

It appears from my testing that the Search extension
(GitHub - radiant/radiant-search-extension: An extension for Radiant CMS to support searching pages.
) is broken in radiant edge.

This is the consistent error:
ActiveRecord::StatementInvalid in SiteController#show_page
Mysql::Error: Unknown column ‘content’ in ‘where clause’: SELECT *
FROM pages WHERE (((LOWER(content) LIKE ‘%aorist%’) OR (LOWER
(title) LIKE ‘%aorist%’)))
RAILS_ROOT: /Users/avonderluft/svn/dev.gknt

And, with a pristine install of radiant edge, and pulling in only the
search extension from github, the result of accessing a search page is:
StandardTags::TagError in SiteController#show_page

Any ideas?
