| method | Choose the way you want to identify similar incidents. Possible values: Indicators, Fields, and Fields and Indicators. | Fields and Indicators | Required |
| handleSimilar | This input defines how to handle similar incidents. Possible values: Link, Close, and Link and Close. Note: Close incidents requires you to define the CloseSimilar input as well. Also, the incidents found by similar indicators or fields will be closed if their similarity score is above the CloseSimilar value. | Link | Required |
| fieldExactMatch | Select the incident field name you want the script to query. For example, if you select 'Type', the playbook will query against the database for all incidents with the same type as your current incident. Note: If you use comma-separated values, the operator between them will be AND. | Optional | |
| fieldsToDisplay | A comma-separated list of additional incident fields to display in the context output. These fields can be used later on for layouts or other states if needed. (Those which will not be taken into account when computing similarity). | Optional | |
| fromDate | The start date to filter incidents. Date format is the same as in the incidents query page, for example, 3 days ago, 1 month ago, 2019-01-01T00:00:00 +0200. | 1 month ago | Optional |

| similarTextField | A comma-separated list of incident text fields to take into account when computing similarity. For example commandline, URL | Required | |
