How to add conditions to thinking-sphinx search?

I've recently installed thinking-sphinx on my ruby on rails app. As first sight, everything works great, I can search words and it will find them. Now, when I try to add some filters(such as, for example, provinces, categories, etc) using:

MyModel.search 'hello' :conditions => 'categor开发者_运维技巧y_id=1' for example, it will throw me the following exception:

searchd error (status: 1): invalid or truncated request

I've been reading some docs on the thinking-sphinx plugin, and I guess I have to do something else than this syntax.

To summarize: until the moment, I just installed the windows service, then I defined a index in one model, and then i tried to search. Again, I succeeded while searching without conditions, but failed while searching with.

Any help will be appreciated.

Thanks, Brian

Assuming your model has category_id:

MyModel.search 'hello', :with => {:category_id => 1}

:conditions is for full text searching specific attributes, :with is for filtering search results.
