What is the pattern format for defining rules?

Each pattern should be on a new line in the format: Label|Pattern|Flags. Flags are optional and include g (global), i (case insensitive), m (multiline), s (dot matches newline), and u (Unicode).

Can I use named groups in my regex patterns?

Yes, patterns with named groups will extract those values in the results, making it easier to identify specific data.

What happens if a pattern has no matches in the text?

By default, patterns with no matches are not shown in the results. You can enable 'Show Empty Patterns' to include them for completeness.

Is there a limit to how many matches are returned per pattern?

You can set a maximum number of matches per pattern using the 'Max Matches Per Pattern' option, which defaults to 50 to prevent overwhelming output.

How are the results organized in the output?

Results are returned as JSON, sorted by match count in descending order, so patterns with the most matches appear first for quick analysis.
