    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()

      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

      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.
