Hi, @gengliangwang and @Yikun

• @gengliangwang , could you update the search engine part, please?
• @Yikun , could you handle DockerHub image parts, please? To avoid the conflicts like the previous one, I didn't publish docker images intentionally.

@dongjoon-hyun Thanks for working on the release!
I have updated and kicked off the crawler. It should be available in one hour.

Thank you so much always, @gengliangwang !
