Is Discourse search immune to typos and how does it work with several words?

For instance, will DC search engine find “John Max Dolittle” with the following queries:

  • hohn <== typo
  • john dolittle <== missing string
  • john mx doelitle <== fuzzy

I was alerted by this post: Discourse search is awfully unsmart!
But it is quite old (2017). Have things improved since?

It seems that the Algolia plug in is no longer official?

AI based search is immune to typos, but it is not fast:

However the technique used means that it is a bit slower cause we need to expand the term using an LLM prior to looking for similarity.

General search stems using snowball: Snowball Stemmer - NLP - GeeksforGeeks

It catches some typos as a side effect, but really this is a side effect thing, we are not using metaphone or other sophisticated typo erasure techniques, there is nothing simple built into postgres for that.

Algolia plugin remains supported and official: Discourse Algolia Search


FWIW the Algolia search plugin is still official :+1:
