Unfortunately new search filters which appear good in terms of visual appearance lacks advance control they used to provide in past. This also means our dating trick will no longer work and you to take lots of efforts to find a right match for you.
Anyway good news is that search filters are now expanded beyond orkut to cover global search filters like county & language specific filtering.
There are some filters now to filter out communities based on some categories which orkut suggests based in your community history. While topic filters are blank as of now. I hope orkut will add more stuff their.
Thanks Sauravjit for the tip.
