I found this old thread, which has now been closed, related to an issue we noticed on our site: Discourse should ignore if a character is accented when doing a search - Feature
In Te Reo Māori in New Zealand, there are two versions of each vowel -- with and without a macron. The macron can change the meaning, but there are some common words used by our community where it would not. These are sometimes typed with the macron and sometimes without, in both topics and search. Therefore, like users in the above thread pointed out, searches including these words yield incomplete results.
I tried to follow the above thread to understand where you got to with this issue but not very clear on the answer. Is it/can it be possible to "ignore" diacritics in search, at least for a specific country or site? Or alternatively, is there any way for us to set this up for a specific list of words?
