I have a website, on that i am searching some strings and got results. By changing the page language the searched contents went out and shows empty page.
I am not sure what you mean by the searched contents went out. Are you saying that after you translated content on your page - your page was empty or search results were empty?
@Ankur_Sial Go to a site, search something on search box--> it shows result --> change the page language to another --> search results went out and shows empty page. But the language changed.
