1. I setting ##1Title in my markdown document.

2. I search 1 in the search input of default theme.

3. It will show an error in my chrome developer tools:

##1Title is not valid markdown (some markdown parses handle it but it looks like the one vuepress uses does not) you should have a space after the last #: ## 1Title

I tried, but it not work.

This can be improved in vue-router. But I've implemented a workaround here for now.

First，you can go to https://github.com/vuejs/vuepress/tree/master/packages/@vuepress/shared-utils/src/slugify.ts to see the config.
And you can modify the file named slugify.js，its path in my computer is D:\my_program\nodejs\node_global\node_modules\vuepress\node_modules\@vuepress\shared-utils\lib\slugify.js, find your own path, and modify it ,you can slove your problem.
