Everybody thanks for your answers!
I found solution by self for "file" option - I can override No result template by file placed to path list_template/includes/search_name/no_result.php
to override it for only concrete Search (named Search_name in example) or list_template/includes/no_result.php
to override it for all L&Searches with this template.
This is all that I could understand individually - if somebody knows more - welcome, explain it to all, please
