How to set up site search on 1C-Bitrix?

Question

PHP

Good evening!
The site contains documents for downloading, the site of a budgetary organization documents such as: resolutions, orders.
The title of the document itself is made a link to the document (when you click on it, the file is downloaded)
Search documents are found but not downloaded, how to make it download?
P/s: Initially, it was revised so that in the settings of each infoblock (where documents are stored) the path to the detailed page was specified: detail.php
and the "News in detail" component was placed in the detail.php file, configured to display the infoblock. Tell me, can there be an option to do so that you don’t have to create a detail.php file for pages with documents every time and configure the component - "News in detail".
