Simplesearch on blog

Support
1

I am not able to do a search in a blog avoiding the /search page of results. I put this on ‘blog.md’:

---
title: 'My blog'
dateformat: 'd-m-Y H:i'
content:
items: '@self.children'
order:
    by: date
    dir: desc
pagination: true
limit: 10
simplesearch:
    route: @self
    filters:
      - '@self.children'
    filter_combinator: and
---

The url is OK: ‘http://my-site/blog/query:word’. But the search result is the entire /blog, does not filter anything.

Also I tried as filter: @self

Any help or tip? Thanks.
