Preserving initial order of the features after filtering in Google Earth Engine

Question

I have some ids as list and I want to filter them in LUCAS dataset. I made a simple example for my problem.

After filtering, I want results as original-initial order of searchList. But after filtering, order of features are not in initial order of searchList. It is important for me to keep initial orders of features.

How can I solve this?

var geometry = ee.Geometry.Polygon(
    [[[26.086635245164302, 41.088934497428085],
      [26.086635245164302, 41.03457263065797],
      [26.14911998637524, 41.03457263065797],
      [26.14911998637524, 41.088934497428085]]], null, false);

var dataset = ee.FeatureCollection("JRC/LUCAS_HARMO/THLOC/V1")
          .filterBounds(geometry)
          //.select('id')

print(dataset)
Map.addLayer(dataset, {}, "LUCAS Points (data)", true);

var searchList = ee.List([950258, 274091, 418881])

var results1 = dataset.filter(ee.Filter.inList('id', searchList))

print(results1)
// results are in order 418881, 950258, 274091

//But results must be in order, 950258, 274091, 418881

One idea is to map a function onto your filtered dataset that sets as a new property the position of id in sortList, which can be then used to sort dataset:

var results1 = dataset.filter(ee.Filter.inList('id', searchList))
  .map(function(feature){
    return feature.set('sortID',searchList.indexOf(feature.get('id')))
    })
  .sort('sortID')
