To filter date in expression rule

you can extract the dates like this 

a!localVariables(
  local!data:"04.01.2022 To 06.30.2022",
  local!Date:split(local!data," "),
  local!ansDate: a!map(start:todate(index(local!Date,1,{})),end:todate(index(local!Date,length(local!Date)))),
 local!ansDate
)

I don't think it can help. The requirement is to filter and with the way the data is stored, it will not be straight forward. 
I have a way to achieve it tho. You will have to create an exactly matching string with your start date and your end date. and then pass that value with the "includes" parameter in the queryFilter()

Thanks for your response.

but my case is like this,local!data : "04.01.2022 to 06.30.2022; 01.01.2020 to 03.31.2020; 10.01.2020 to 06.30.2022; 07.01.2021 to 06.30.2022"

Yes it is possible you can apply the selection the particular column and use >= and <= to fetch the data between two dates and concat them using to string.

Your query will be like this

  a!queryEntity_22r2(
    entity: cons!AA_VEHICLES_DSE_POINTER,

    query: a!query(
      selection: a!querySelection(
        columns: a!queryColumn(
          field: "vehicleDateAdded"
        )
      ),
      logicalExpression: a!queryLogicalExpression(
        operator: "AND",
        filters: {

          a!queryFilter(
            field: "vehicleDateAdded",/*field Name*/
            operator: ">=",
            value: ri!startDate
          ),
          a!queryFilter(
            field: "vehicleDateAdded",/*field Name*/
            operator: "<=",
            value: ri!endDate
          )
        },
        ignoreFiltersWithEmptyValues: true
      ),
      pagingInfo: a!pagingInfo(
        startIndex: 1,
        batchSize: 10
      )
    ),
    fetchTotalCount: false
  ).data

Thanks for responding back.

I am not getting your point,could you please explain?

Data : "04.01.2022 to 06.30.2022; 01.01.2020 to 03.31.2020; 10.01.2020 to 06.30.2022; 07.01.2021 to 06.30.2022"

RuleInput1 : Jan 1 2020

RuleInput2 : Mar 31 2020

Expected Output: Above data i should get as a result

concat(text(local!date1,"mm.dd.yyyy")," to ",text(local!date2,"mm.dd.yyyy"))

You can now pass this value 

Thank you. But I am facing this below error,

a!queryFilter(
    field: "parIncludedPeriods_txt",/*field Name*/
    operator: "includes",
    value: concat(text(local!date1,"mm.dd.yyyy")," to ",text(local!date2,"mm.dd.yyyy"))
  )

Change the variables date1 and date2 with your original onces. 

 I tried now. This works fine. Many thanks Harshit !!
