thinking sphinx 搜索结果为空5

建立索引，有结果，但搜索时就结果为空了，为啥。

model定义如下
class Caipu < ActiveRecord::Base

    define_index do
        indexes :title
        indexes :description
        indexes :keywords
        indexes :content
        has id,created_at,updated_at
        set_property :delta => true
    end
end

这是建立索引的日志
[root@localhost cp]# rake thinking_sphinx:index
