Document alias problem with ajax search

I have a problem with ajax search

I created few documents with their alias. some documents are on root level and some documents are under parent document.

When i search any document using ajax search from root level document, search work fine. But when i do search from document under any parent document then search will not work and redirect me to modx start page.

But if i use document id in url instead of document alias then search works fine.

Example:

Search works correctly in urls like
http://www.brilliantstaging.com/ki-mobile/

Not work in url like
http://www.brilliantstaging.com/ki-mobile/about-mobile-marketing/about-ki-mobile.html

I download ajaxsearch 1.7.1 and also set permission of every folder to 777.

Please help me in solving this problem..................
