Broken search for Transformers library feature for query: "ConfidenceCriteria"

[lukestanley]

Bug description.

1. Go to https://huggingface.co/docs/transformers/index
2. Click the input field on the left side, where it says "Search documentation"
3. Enter a "ConfidenceCriteria"
4. No result found!

Describe the expected behaviour
I expect to the library's official documentation site to correctly show search results, just like this search does:
https://github.com/search?q=repo%3Ahuggingface%2Ftransformers+ConfidenceCriteria&type=code

Additional context

It could be an issue with Meilisearch.
Many other searches work, DO work.
I am using Firefox 131.0.3 (64-bit) on Ubuntu, but this is unlikely a browser bug since many other searches work fine.
