Advanced Search
Visual query builder that empowers investigators to create multi-dimensional searches — transforming advanced intelligence gathering into an accessible, intuitive process. No need to write a single line of code.
Industry-First Capabilities
Complex threats demand complex queries, but complex doesn't have to mean complicated. Advanced search transforms the intricate logical relationships that reveal sophisticated attack patterns into visual, drag-and-drop workflows that make sense to human minds, not just database engines.
Build complex logical queries by connecting visual elements instead of memorizing syntax. Drag conditions, drop operators, and watch your investigation logic take shape in real-time—no SQL manual required.
Industry-First InnovationBuild the complex logical relationships that reveal sophisticated attack patterns. Nested operations let you construct queries that mirror how real threats actually unfold—with multiple conditions and exceptions that basic searches can't handle.
Enterprise GradeOur engine rewrites your visual logic into optimized database queries behind the scenes. Automatic condition reordering and index optimization mean you get enterprise performance without database administration expertise.
AI-PoweredMastering the Query Builder Interface
Security investigations don't follow simple patterns, so why should your search interface? The query builder transforms complex logical thinking into visual workflows, eliminating the cognitive overhead of syntax memorization while preserving the full power of advanced database operations.
Rule Groups
The building blocks of complex logic. Groups let you organize related conditions and apply different logical operators to different parts of your investigation, mirroring how you actually think about threats.
Individual Rules
Individual search conditions that form the foundation of your query. Each rule asks a specific question about the data—combine them to build sophisticated investigative logic.
Control Elements
The tools that let you shape your investigation logic. Add conditions, create nested groups, and restructure queries with clicks instead of complex syntax manipulation.
Step-by-Step Construction Guide
Master advanced query construction through our systematic approach, designed to minimize complexity while maximizing investigative capability. This methodology scales from simple multi-field queries to enterprise-grade data mining operations.
Initial Query Planning & Strategy Development
Complex queries can quickly become unwieldy without clear objectives. Define what you're hunting for before you start building—it's the difference between surgical intelligence and expensive data fishing expeditions.
Root Rule Group Initialization
Start with your strongest, most specific condition as the foundation. Build from high-confidence data points outward—this approach minimizes processing time and maximizes result relevance.
Logical Structure Construction
Layer your logic thoughtfully. AND operations narrow your focus for precision targeting, while OR operations widen the net for comprehensive coverage. Each choice shapes your investigative approach.
Query Validation & Execution
Your sophisticated query logic is worthless if it's logically flawed. Review the natural language preview to catch errors before they waste precious quota, then execute with confidence that your investigation approach is sound.

Strategic Investigation Use Cases
Advanced search transforms theoretical query capabilities into practical investigative workflows, enabling security professionals to conduct sophisticated analyses that were previously limited to database specialists and advanced researchers.
Executive exposure assessment requires surgical precision. Build multi-layered queries that capture every angle of high-value target compromise while filtering out the noise that wastes critical investigation time.
(email contains "@company.com" AND name contains "CEO") OR (username starts with "exec" AND breachdate > "2023-01-01") AND NOT (breachsource contains "spam")
Strategic Applications:
- C-suite compromise assessment
- Board member exposure analysis
- Executive travel security preparation
- Merger & acquisition due diligence
When systems are compromised and every minute counts, you need intelligence that cuts straight to the scope of the problem. Advanced search delivers the critical context that determines whether you're dealing with a targeted attack or widespread compromise.
(email contains "@targetdomain.com" AND breachdate > "2024-01-01") AND (password is not empty OR phone is not empty) AND NOT (breachsource contains "historical")
Operational Benefits:
- Recent breach correlation analysis
- Attack vector identification
- Lateral movement risk assessment
- Credential overlap detection
Threat actors leave patterns across their campaigns—if you know how to look for them. Advanced search reveals the connections between seemingly unrelated breaches, exposing attribution markers that basic searches miss completely.
((username contains "hacker" OR username contains "admin") AND password regex "^[A-Z]2[0-9]4$") OR (breachsource contains "darkweb" AND name is not empty)
Intelligence Applications:
- Campaign infrastructure mapping
- Attacker methodology analysis
- Cross-breach pattern recognition
- Attribution confidence scoring
Compliance isn't just about ticking boxes—it's about proving due diligence with bulletproof methodology. Advanced search provides the documented, reproducible analysis that satisfies auditors and regulators who demand evidence-based security practices.
(login ends with ".gov" AND login_type equals 0) AND (password is not empty OR login_type equals 1) AND (breachdate > "2018-05-25")
Compliance Scenarios:
- GDPR impact assessment
- PCI DSS scope determination
- HIPAA breach notification requirements
- SOX internal control validation
Professional Best Practices & Optimization
- Start narrow, expand strategically—restrictive conditions first saves processing power
- Field-specific searches beat generic text matching every time
- Trust but verify—always check the query preview before execution
- Save sophisticated queries as templates for team reuse
- Count first, search second—especially for complex patterns
- Document your methodology—auditors and compliance teams will thank you
- Watch your quota like investigation budget—it matters
- Export immediately—findings disappear when quotas run out
- Deep nesting kills performance—keep it under 4 levels
- Indexed fields first—let the database work smarter, not harder
- Specific operators over broad patterns—precision beats brute force
- Complex regex patterns look smart but run forever
- Watch performance indicators like a performance dashboard
- Order conditions by selectivity—filter aggressively early
- Balance thoroughness with speed—perfect is the enemy of good enough
- Cache repeated patterns—why rebuild what already works?
- Building complex queries when simple ones would work—complexity for complexity's sake
- Ignoring logical precedence—your query means what the parser thinks it means
- Regex patterns that look impressive but crush performance
- Skipping query validation because you're in a hurry
- Row limits set to maximum because "more is better"
- Rebuilding queries that teammates already perfected
- Complex queries with zero documentation—good luck debugging later
- Quota consumption surprises during time-critical searches
