Query task based on payload (urgent and not getting any solution)

Question

Hi, I m creating a task in BPEL process with following payload.
<?xml version="1.0" encoding="UTF-8"?>
<schema attributeFormDefault="unqualified"
elementFormDefault="qualified"
targetNamespace="http://xmlns.oracle.com/RegistrationUpload_jws/RegistrationUpload/OfficerList"
xmlns="http://www.w3.org/2001/XMLSchema">
<element name="process">
<complexType>
<sequence>
<element name="jobAssignmentType" type="string"/>
<element name="officerLevelNum" type="string"/>
<element name="applicationType" type="string"/>
<element name="functionId" type="string"/>
<element name="app_id_val">
<complexType>
<sequence>
<element name="key" type="string"/>
<element name="value" type="string"/>
</sequence>
</complexType>
</element>
<element name="dcConservationFlag" type="string"/>
</sequence>
</complexType>
</element>
</schema>*
Now i want to use queryTask with function
List tasks = querySvc.queryTasks(ctx, queryColumns, null, //Do not query additional info
ITaskQueryService.AssignmentFilter.MY,
null, //No keywords
null, //No custom predicate
null, //No special ordering
0, //Do not page the query result
0);
My query is i want to query the tasklist based on paylod item as dcConservationFlag="N" and functionId="1001" so how I will set the code.
My feeling is somewhere we need to set it in predicate class. but not sure how to do that.
can anyone please guide me for this.

Answer 1

if you want your task searchable, you should use flex-attributes. you should find it in /task:task/task:systemManagedAttributes
during search you can use query like this column=textAttribute1
