Usage

3. Enter your filter pattern using the following syntax:

Basic pattern:
    "pattern"                    - Matches lines containing "pattern"

Wildcards:
    "test*"                     - Matches lines containing text starting with "test"
    "*test"                     - Matches lines containing text ending with "test"
    "*test*"                    - Matches lines containing "test" anywhere

Logical operators:
    "pattern1" and "pattern2"   - Matches lines containing both patterns
    "pattern1" or "pattern2"    - Matches lines containing either pattern

Complex expressions:
    ("error*" or "*failed") and "2024"   - Matches lines from 2024 containing either
                                          text starting with "error" or ending with "failed"

Examples

• "error" - Find lines containing "error"
• "*ERROR*" or "*WARN*" - Find lines containing ERROR or WARN
• "2024-01*" and "ERROR" - Find error lines from January 2024
• ("HTTP*" or "TCP*") and "*failed*" - Find failed HTTP or TCP related lines
