The Search window returns assets with unrelated names with a single character query

Reproduction steps:

1. Open the “kun” project
2. Press CTRL + K
3. In the Search window type “4. t:scene”

Expected result: One scene appeared in the search results
Actual result: 20+ scenes appeared in the search results with names unrelated to the query

Reproducible with: 2021.3.12f1, 2022.1.20f1, 2022.2.0b12, 2023.1.0a15
Could not test with: 2020.3.40f1 (The Search window is not introduced)

Reproduced on: Windows 10

Note: This happens when Advanced Search for project is enabled in preferences and when searching in the project browser.

Note: issue also reproduces in the Project window with enabled Advanced search mode. Deleting and generating the Library folder eliminates the issue
