I search for "中華丼" and I get couple of cards. I check the first card but there is no "中華丼" but "中華". In this case, the first card should not be listed in the query result.
I am using the latest 64 bit Google Chrome 62.0.3202.94（Official Build） on 64 bit Japanese Windows 10 Pro (v1703, OS build 15063.726). I have tried both English and Japanese Trello UI but it will not fix the issue.
We haven't been able to reproduce this so far. Do you know if "中華丼" is included anywhere on that other card, even in a comment? Since we search all of the card content, not just the title, it would be included in the results if it contained that anywhere.
If you create a new card with just "中華" on it, does that also show up in the search?
