Walkthrough
The recent updates introduce a MatchesFunction for full-text search functionality in the matches.rs file. This includes parsing search patterns, constructing an abstract syntax tree (AST) for pattern matching, and evaluating these patterns against input data using DataFusion. Additionally, minor edits were made to the typos.toml configuration file.

Beneath the code, in lines we'll find,
A function born of thoughtful mind.
It parses text, both swift and keen,
To find the match where none had been.
With DataFusion's helping aid,
A search is done, the quest well paid.
For rabbits know, in fields of green,
The best of code, is sharply seen. 🎩🐇✨

Early access features: enabled
We are currently testing the following features in early access: - **OpenAI `gpt-4o` model for code reviews and chat**: OpenAI claims that this model is better at understanding and generating code than the previous models. We seek your feedback over the next few weeks before making it generally available. Note: - You can enable or disable early access features from the CodeRabbit UI or by updating the CodeRabbit configuration file. - Please join our [Discord Community](https://discord.com/invite/GsXnASn26c) to provide feedback and report issues. - OSS projects are currently opted into early access features by default.
Thank you for using CodeRabbit. We offer it for free to the OSS community and would appreciate your support in helping us grow. If you find it useful, would you consider giving us a shout-out on your favorite social media?
