Ruby on Rails

I have a 2 entities which have many to many relation say teacher and subject. Each teacher has many subjects. I want to perform search on teacher by sunspot solr for all the teacher who teaches 3 subjects biology, anatomy and botany with specific time.

----------

Say model structures and relations as follows

    Teacher - name, roll, ph no

    has many :subjects

    searchable do 

      string :subjects, multiple => true, stored => true do

       subjects.map(&:title)

      end

      string :time, multiple => true, stored => true do

        subjects.map(&:time)

      end

    end

    Subject - title, time, teacher_id

    belongs_to :teacher

How would I perform solr search query for the teachers who are having all 3 subjects biology, anatomy and botany at time 3:00pm.

I am trying with following code which is not taking and condition to retrieve only the teachers teaching all the 3 subjects rather its taking as or condition.

    Sunspot.search(Teacher) do

      with(:subjects, "biology")

      with(:subjects, "anatomy")

      with(:subjects, "botany")

      with(:time, "3:00pm")

    end.results
