Jabid Dakta, as you know the Oxwall is the social networking software platform. The modifications you are talking about are more related to the dating sites. But for social networking sites unlimited search options are more preferable.
 In your case I guess it would be interesting for you to take a look at the Skadate X software.

OK, ok. Since I have two powered oxwall sites (one is oxwall, the other is skadate X) I thought I could get the answer in a much more prolific forum...:(

So you mean I cannot set up a dating site with Oxwall ??

Jabid Dakta, Oxwall is unbelievably flexible social networking software platform and you may use it in any way you need, including as a dating site. And it is acceptable that it may require some custom code modifications and plugin development. So I advised you the Skadate X software because if you focused on the dating sites then the Skadate X may fit all your needs with its special aimed plugins.

Or if you would like to modify the Oxwall platform you can post your issues  in the Custom code modification forum or to find a developer who can help you with the plugin development.
