Proximity: 300 characters

Should match

• Backup catalogs — Exact phrase marker match
• backup catalogs — Case-insensitive phrase match
• Backup catalogs — Normalized whitespace phrase
• structured sample with matching anchors — Structural anchor sample

Should not match

• unrelated generic text — No relevant phrase context
• placeholder value 12345 — Random text should not match phrase marker
• generic policy prose without anchors — Should reject generic mentions without structural anchor terms
• template example placeholder record identifier — Template/sample context should be excluded even when anchor words are present

Known false positives

• Authentication-related terminology in software documentation, security training materials, or system architecture descriptions without actual credentials. Mitigation: Require proximity to credential-specific patterns (API keys, connection strings, tokens) rather than general security terminology.
• Code snippets and configuration examples containing credential-related keywords or placeholder values in developer documentation. Mitigation: Check for common placeholder patterns (example.com, localhost, 0000) and documentation file types to reduce false positives from technical writing.
