Minimal RegEx Matcher:
- Accepts pattern and flags
- Outputs "1" if match is found, else "0"
- No visual output display
Test for text matches with a regular expression pattern.
- Accepts a regex pattern and flags (e.g. "i", "g", "m")
- Connect any node to the input to test its value.
- Outputs "1" if the regex matches, otherwise "0".
- Useful for input validation, filtering, or text triggers.

### Regex Search Node
This node tests its input value against a user-supplied regular expression pattern.
**Configuration (Sidebar):**
- **Regex Pattern**: Standard JavaScript regex pattern.
- **Regex Flags**: Any combination of \`i\` (ignore case), \`g\` (global), \`m\` (multiline), etc.
**Input:**
- Accepts a string from any upstream node.
**Output:**
- Emits "1" if the pattern matches the input string.
- Emits "0" if there is no match or the pattern/flags are invalid.
**Common Uses:**
- Search for words/phrases in extracted text.
- Filter values using custom patterns.
- Create triggers based on input structure (e.g. validate an email, detect phone numbers, etc).
#### Example:
- **Pattern:** \`World\`
- **Flags:** \`i\`
- **Input:** \`Hello world!\`
- **Output:** \`1\` (matched, case-insensitive)
