If direct entity search isn't supported, use broader filters and refine results. ### Step 2: Execute Search ``` secops-soar.list_cases( filter=constructed_filter, limit=MAX_RESULTS ) ``` ### Step 3: Process Results Extract case IDs and basic details (DisplayName, Priority) from results. ### Step 4: (Optional) Refine Results If too many results, use `get_case_full_details` on a subset to verify entity presence: ``` secops-soar.get_case_full_details(case_id=candidate_case_id) ``` ## Outputs | Output | Description | |--------|-------------| | `RELEVANT_CASE_IDS` | List of case IDs that match the search | | `RELEVANT_CASE_SUMMARIES` | Brief summaries (ID, name, priority) | | `FIND_CASE_STATUS` | Success/failure status of the search | ## Limitations & Workarounds The `list_cases` tool may not support direct entity searching. Alternatives: 1. **Broader filters** - Use time range, alert type, then manually review 2. **SIEM correlation** - Search SIEM for entity, check if events belong to a case 3. **Multiple searches** - Search each term separately, combine results
