Hi Komal,

You need to update the expression ucArrayPickerFilter,

=with(
  local!matches: where(
    a!forEach(
      items: ri!labels, 
      expression: like( fv!item,ri!filter&"*")
    )
  ),
  a!dataSubset(
    data: index( ri!labels, local!matches), 
    identifiers: index( ri!identifiers, local!matches)
  )
)

I used LIKE function instead of SEARCH

Hi,

You'll want to update the logic within rule!ucArrayPickerFilter. If you're using the example from the SAIL Recipe (docs.appian.com/.../recipe_configure_an_array_picker_that_ignores_duplicates.html), that expression rule uses fn!search to return any of the labels that match the input anywhere within the label. Instead of using search, you could update that rule to use something like "left(fv!item, len(ri!filter)) = ri!filter" to actually check if the item starts with exactly what's been typed in by the user.

Thanks,
Dan
