Search Behavior

The search function performs intelligent matching across multiple fields:

• Domain matching: Searches primary domains and additional domains
• Company name matching: Searches official company names and alternative names
• Subsidiary matching: Searches subsidiary names and domains
• Stock symbol matching: Searches stock ticker symbols

The search uses both regex pattern matching (for prefix matching) and full-text search to provide comprehensive results.
