Thank you Brenden, for your prompt reply.
Yes, I have set search properties on the custom table and also built the index.
I noticed, there was a problem in search index.
I did change in search type from Simple to Subset and rebuild the index. Now, search functionality working fine.
But still, when I click on searched result, system navigating on same page instead on actual page where I have register web part.
There are ten different page in my website.
Webpage1, Webpage2, .......Webpage10
I have registered my web part in Webpage10 and Smart search web part in Webpage1, then searched with one keyword, I got 3 results, now click on searched result link from Webpage1, system should navigate on Webpage10 instead of on Webpage1
If anyone have idea about this problem. Please post answer soon.
Thanks with regards,
