Hi Peter
Currently, Thinking Sphinx doesn't support spell-checking - it's not a
Sphinx feature, although I can see how it would be useful. I've had
someone submit a patch for aspell support, closely modeled on how
Ultrasphinx did it, but at this point in time it's not a high
priority. The ideal solution is to allow for it, but make sure it's
unobtrusive (so if aspell/raspell isn't installed, everything's still
fine - which is probably how the patch works anyway, but just wanted
to be explicit about this).
As for concatenation, Thinking Sphinx does this very simply:
indexes comments.body, :as => :comments
If you wanted to have those conditions wrapped in, I'd recommend
making a separate association, say, active comments:
has_many :active_comments, :class_name => "Comment", :conditions =>
"approved = 't' AND spam = 'f'"
And then have the following field declaration:
indexes active_comments.body, :as => :comments
As for searching across models, you can do that simply as follows:
ThinkingSphinx::Search.search "query", :classes => [Post, User]
Hope this helps - and sorry for the delay in getting back to you.
Cheers
