questions about search and Permalink

Hi, first of all many thanks for this plugin,

I have so many questions and issues:

1- The search function it’s not working will with arabic character.

2- is there any way to change the status of any new question as Draft or un-publiched until i a prove it?

3- My Permalink for any posts “domain/title_of_post” so is there any way make the Permalink for any question as “domain/slug/NUMBERS” i don’t want it like my posts Permalink.

Regards,,
