How can I refine a search query using operators?

------------
A wildcard that can represent any extension of letters. It does not work with dates or numbers.
Examples
*one
Finds documents containing bone, cone, clone, crone, done, drone, gone, telephone (and any other words of any length that end with 'one').
Also,
*one*
Finds documents containing bone, cone, clone, lonely, phoned, stoned, pardoned.
------------
However, for this wildcard, it does not work correctly for Japanese searches.
For Example:
1. Create new documents containing each of the following words.
リンゴ
リンゴ酢
2. Create Full Text Index in the database.
3. If Notes user try to search "リンゴ" by full text search in search bar for full text search, all documents are hit.
4. However, if Notes user Notes user try to search "リンゴ*" with Wildcard, no documents are hit despite the existence of those documents with the word "リンゴ".
This result would be very inconvenient for Japanese users.
Therefore, we would like wildcards to work for Japanese word searches as well.
That sounds like a bug, can you please open a support ticket to investigate this further?
