[bug] Font search does not work as expected

[spartan-uyen]

Summary:
The font search feature returns incorrect results. When searching for a full font name (e.g., "Adlam Display"), the search returns any font that contains part of the term (e.g., fonts with just “Display”), instead of matching the full query string.

Steps to reproduce:

1. Open the font panel.
2. In the search input, type a full font name such as "Adlam Display".

Actual result:
Fonts that only contain "Display" appear in the results, including ones that do not contain "Adlam".

Expected result:
Only fonts that match the full search string, such as "Adlam Display", should be shown in the results.
