Describe the bug

A specific Chinese phrase "生电" (short for 生存实用电路, a vanilla redstone gameplay style) used to correctly return the modpack "红石生电优化【Redstone Survival Optimization】" by author "moonboss666". However, this search now fails completely — the expected result does not appear at all.

This appears to be a regression; the search was working correctly for this query in the past.

Steps to reproduce

1. Go to Modrinth.com
2. Type "生电" in the search bar and press Enter
3. Observe that the modpack "红石生电优化【Redstone Survival Optimization】" by "moonboss666" does not appear
4. As a further check, search the full title "红石生电优化" — confirm if this also fails

Expected behavior

Searching "生电" should return "红石生电优化【Redstone Survival Optimization】" in the results, as it did previously. Exact substring matching on project titles should work regardless of language.

Additional context

• This is a regression: this exact search worked before.
• The issue affects Chinese-speaking players who use community-standard abbreviations like "生电" to find redstone survival content.
• I don't speak English; this message was translated for me.
• Browser: Chrome
