Thanks for the hint! Unfortunately it doesn’t solve the problem
It’s quite weird that some pre-2.3 posts contain search URLs (some has multi-word search terms with different accents) which are working fine and return valid result while new search queries are not working and give back not relevant posts.
Unfortunately accents can’t be ignored because it would result in inaccurate results. Where should I look to fix this issue? Maybe downgrading back to 2.2 (it’d be just a temporary fix though )?
I’ve made a fresh local install and “kávé” worked OK but some other words did not. It seems the problem is related to the full text search in PostgreSQL and how the text is parsed. For example from search word “kávé” will be “ká” after normalization and that normalized form will be matched to the text so “kávé” and “káposzta” are both correct results for the FTS
I hope the situation will improve with using hunspell dictionaries in PostgreSQL but currently the Hungarian one is broken
