docs: Add a filter using "IN" logic. This is typically the primary filter
          that will be used to find a match and generally combines other
          filters to get more granular. An example of usage would be searching
          for an IP address (or addresses) in a specific log field. Or looking
          for an IP address in multiple log fields.
