Anki’s search functionality does not currently support ignoring accents or formatting outside the sort field due to technical reasons, but it is something I’d like to address in the future.
I found this old topic and wonder if the time for this has come
The ignore accent addon doesnt work very well and nc:
is incompatible with w:
on top of having to type it on every search
Would it be possible to add a toggle somewhere? pretty please?
