Launching regex search support
You can now search in Chroma using regular expressions.
Regex search enables you to:
| Use case | Example regex |
|---|---|
| Identify function calls in code | \b\w+\( |
| Find email addresses inside any document | [A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,} |
| Extract TODO comments in code | TODO[: ] |
| Locate US phone numbers | \(?\d{3}\)?[-.\s]?\d{3}[-.\s]?\d{4} |
| Check for URLs | https?://[^\s]+ |
API#
To run a regex search, apply the $regex or $not_regex operator on the where_document field in a .query or .get.
Example#
Here is an example in Python:
Regex support is also now directly supported in the Chroma Cloud UI.
