def self.filter_by(data_type, min, max, missions_set=false)
  missions_set ||= Mission.all

  missions_set.where(data_type => min..max)
end

def self.filter_by_title_fragment(fragment, missions_set=false)
  missions_set ||= Mission.all

  missions_set.where("title LIKE ?", "%" + fragment + "%")
end

Simple database-level filtering allows for filter chaining:

params[:search][:min_lat] && @missions = Mission.filter_by(
  :latitude, params[:search][:min_lat], params[:search][:max_lat], @missions
)

params[:search][:min_lng] && @missions = Mission.filter_by(
  :longitude, params[:search][:min_lng], params[:search][:max_lng], @missions
)

params[:search][:title] && @missions = Mission.filter_by_title_fragment(
  params[:search][:title], @missions
)
