Hi Prashant,
According to your description, my understanding is that the search cannot work correctly when crawling the SharePoint site which is form-based authentication.
Per my knowledge, the crawl component requires NTLM to access content. At least one zone must be configured to use NTLM authentication. If NTLM authentication is not configured on the default zone, the crawl component can use a different
zone that is configured to use NTLM authentication.
However, if crawling a non-default zone of the web application, URLs of results will always be relative to the non-default zone that was crawled for queries from any zone, and this can cause unexpected or problematic behavior.
I recommend to make sure that the default zone of the SharePoint 2010 web application to use NTLM authentication.
