functions expression rules

Hi there,

I do not understand this part.

should be come randomly

But what I think is that, when you search for 5, you should get a question with id as 5. 
For that, you use queryFilter() in query(). Documentation - https://docs.appian.com/suite/help/21.4/fnc_system_a_queryfilter.html

If you want to combine it with any other filter, then try using logical expressions in query() function where you can pass multiple filters that can be applied all at the same time, or any of them. 

I hope it helps. 

Thanks,

it should come randomly means if there are 10 questions I want only 5 questions that is like not comes in ordering it should be like {10,1,5,3,8}

Hi there,

This can be another approach. You generate a list of incremental random values, all unique. And then use that array to index from the list of available questions. 

Below is the code for the same. 

a!localVariables(
  local!questionsData,
  local!array: 1 + tointeger(rand(5) * (1000 - 1)),
  local!sortedArray: rule!BAM_utils_sortArray(
    arrayValues_any: local!array,
    ascending_bool: true
  ),
  local!randomIndex: a!flatten(
    a!forEach(
      items: local!sortedArray,
      expression: wherecontains(fv!item, local!array)
    )
  ),
  index(
    local!questionsData,
    local!randomIndex,
    {}
  )
)

In local!array, I am trying to generate the values in a specific range. The parameter of rand() function will give us 5 values. You can change it to n.
