Hacker News search bug?

Urls here for clickability:

https://hn.algolia.com/?query=confused%20lost%20mathe

https://hn.algolia.com/?query=mathe%20confused%20lost

My guess is that they assume that all but the last words are complete, so the first query is read as

confused lost mathe??????????

and the second as

mathe confused lost??????????

but an space at the end is enough to break the fist link: https://hn.algolia.com/?query=confused%20lost%20mathe%20

I looked at the algolia site, but I couldn't find an email for contact ...

By default the search will consider the very last word as a "prefix" to handle the as-you-type search experience. If you press enter in the searchbar oh hn.algolia.com, it will "fix" such behavior considering the last word as an actual word.

Notice the "prefix=false" in the URL: https://hn.algolia.com/?query=confused%20lost%20mathe&sort=b...
