        "description": "**Core Function**: Intelligent hybrid search with keywords and regular expressions, solving keyword order limitation problems.\n\n**Applicable Scenarios**: Comprehensive content retrieval of pagination.txt files when extended keywords are obtained.\n\n**Advantages**:\n- Does not depend on keyword occurrence order, more flexible matching\n- Sorts by number of matched keywords, prioritizing most relevant results\n- Supports mixed use of regular keywords and regular expressions\n- Intelligently recognizes multiple regex formats\n- Enhanced result display with match types and detailed information\n- Output format: `[line_number]:[match_count]:[match_info]:[original_line_content]`\n\n**Supported Regex Formats**:\n- `/pattern/` format: e.g., `/def\\s+\\w+/`\n- `r\"pattern\"` format: e.g., `r\"\\w+@\\w+\\.\\w+\"`\n- Strings containing regex special characters: e.g., `\\d{3}-\\d{4}`\n- Automatic detection and intelligent recognition of regex patterns\n\n**Match Type Display**:\n- `[keyword:xxx]` Shows regular keyword matches\n- `[regex:pattern=matched_text]` Shows regex matches and specific matched content\n\n**Use Cases**:\n- Composite condition searches: Scenarios requiring matching multiple keywords and regex simultaneously\n- Unordered matching: Data retrieval where keyword occurrence order is not fixed\n- Pattern matching: Complex data retrieval needing specific formats (email, phone, date)\n- Relevance sorting: Prioritize most relevant results by match degree\n- Hybrid retrieval: Advanced search combining keyword exact matching and regex pattern matching",
