The query url does not work for my site

[yanglr]

Hi, My site https://dbdgs.cn is built with the vuepress theme Vdoing.

I install and config like the steps you write.

The expected query url https://dbdgs.cn?query=javascript will be redirected to https://dbdgs.cn/?query=javascript, and does not filter with any post back (always show all posts), actually I have some posts contains "javascript". Could you help me have a check? Thanks~

My repo is https://github.com/dbdgs/dbdgs.github.io, deployed in github pages using github Action (Using node v12).

config.js: https://github.com/dbdgs/dbdgs.github.io/blob/main/docs/.vuepress/config.js
