hi, I'm trying to understand how to index geospatial field which is linestring. In the example you use stPoint, is there stLineString?

{
  "dataType": "BYTES",
  "name": "location_st_point",
  "transformFunction": "toSphericalGeography(stPoint(lon,lat))"
}

someting like that?

{
  "dataType": "BYTES",
  "name": "location_linestring",
  "transformFunction": "toSphericalGeography(stLinestring(arr))"
}
