How to remove title from search module?

Hello Ivan,

No success...Could you guide me the html file location <div class="search"> <h1> Search </h1> I will remove it?

No you can not remove that, page title is basic thing and you would affect all of site pages. So you must have search menu item in at least one menu, if you have multiple make second , third... alias of that one menu item. Then in that search page menu item under Page Display Options set Show Page Heading to NO
