Camunda task search

I am using Camunda version 7.19.0. I have implemented a controller that takes a TaskQueryDto to find all tasks based on specified variable criteria.

@RestController
public class RestEngineController {

    @Autowired
    private TaskCustomService taskCustomService;

    @PostMapping(value = "/rest-engine/task-with-variables", produces = MediaType.APPLICATION_JSON_VALUE)
    List<TaskWithVariables> getTasks(@RequestBody TaskQueryDto query,
                                     @RequestParam("firstResult") Integer firstResult,
                                     @RequestParam("maxResults") Integer maxResults) {
        return taskCustomService.getTasks(query, firstResult, maxResults);
    }
}

However, I’ve encountered an issue. In Camunda’s ConditionQueryParameterDto , there is no operator for “in”.

public class ConditionQueryParameterDto {

  public ConditionQueryParameterDto() {

  }

  public static final String EQUALS_OPERATOR_NAME = "eq";
  public static final String NOT_EQUALS_OPERATOR_NAME = "neq";
  public static final String GREATER_THAN_OPERATOR_NAME = "gt";
  public static final String GREATER_THAN_OR_EQUALS_OPERATOR_NAME = "gteq";
  public static final String LESS_THAN_OPERATOR_NAME = "lt";
  public static final String LESS_THAN_OR_EQUALS_OPERATOR_NAME = "lteq";
  public static final String LIKE_OPERATOR_NAME = "like";
  public static final String NOT_LIKE_OPERATOR_NAME = "notLike";

So, how can I use the “in” operator?

Hi @pertsh.galstyan
This boils down to the same answer as for your other question.
There is no possibility to do an OR or IN search, so you will have to do multiple requests to achieve this.
