I see you solved the word match problem. I believe you had the “AND with exact keyword matches” keyword logic selected on the General Options -> Behavior panel.
As for the croatian translation for the “Search breed…” text I recommend this very simple solution:
1. Make a duplicate of the search instance: https://i.imgur.com/FYyO2Fj.png
2. Edit the “Search breed…” and any other text in this new search instance to croatian.
3. Use this new search shortcode in the croatian version of the article 😉
