Question

我希望能够列出1000个结果，但由于ASC限制与宝石思维狮身人面像，我被限制在20个。

如何增加ASC限制0,20到0,1000？

SELECT GEODIST(0.5904448859496816, -1.464156709498043, latitude, longitude) AS geodist, * 
FROM `location_core` 
WHERE `geodist` BETWEEN 0.0 AND 200000.0 AND `sphinx_deleted` = 0 
ORDER BY `geodist` ASC 
LIMIT 0, 20

这是我必须用MYSQL修改的吗？

控制器：

  def index
       location  = Location.find_by_zipcode params[:zipcode] 
        latitude  = location.latitude * Math::PI / 180 
        longitude = location.longitude * Math::PI / 180 

        location_ids = Location.search_for_ids( 
          :geo   => [latitude, longitude], 
          :with  => {:geodist => 0.0..200_000.0}
        ) 
        @users = User.where(:location_id => location_ids)        
      end

Answer 1

ASC 0,20很好。

更改

 :geo   => [latitude, longitude], 
          :with  => {:geodist => 0.0..200_000.0}

到

  :geo   => [latitude, longitude], 
  :with  => {:geodist => 0.0..200_000.0}, 
  :per_page => 1_000

增加搜索结果的ASC限制条款
