Totally agree with this no-code solution.

Moreover, I use https://hn.algolia.com search engine to filter stories by type ("Show HN") and sort by date.

Query example: https://hn.algolia.com/?dateRange=pastWeek&page=0&prefix=tru...

Another useful link to "Advanced search syntax": https://hn.algolia.com/help

Edit: It appears that Algolia search engine has several hours delay in indexing. But it is acceptable to me.
