Weird article often being matched in search queries

[MrOrz]

This particular message is very "popular":
https://cofacts.g0v.tw/article/tibj83yu5zyr

The URL does not make any sense, but it somehow matched in many search queries, so that our chatbot users often clicks it:

After searching tibj83yu5zyr in chatbot logs, the following URLs would trigger such response

• https://bre.is/VEkmdEtb
• https://www.zeczec.com/projects/flashget-ssd-1tb-20

However, the chat log shows that the article is also in search results of the following search queries, but I cannot reproduce them now:

• http://www.oqrms.com/article/SStCUGJvZmQ2Q0E9#jiege3
• http://news.ltn.com.tw/news/life/breakingnews/3026197
• ttps://www.edh.tw/article/12993/2

TODO

1. Investigate why the query match / doesn't match
2. Maybe add a flag to articles to restrict particular messages from being searched (?)
