LeaFlet + LeaFlet.search + GeoJSON, search across multiple marker sets?

Question

JavaScript

Hello dear community.
Trying to figure out " LeaFlet JS". With the output of the map itself and markers, everything is clear, but with LeaFlet.search I can’t solve problems.
Two sets of markers are superimposed on the map, in turn, I get them from a GeoJSON file
GeoJSON example

{
"type": "Feature",
"properties": {
  "name": "Что-то этакое",
  "category": "категория 1",
  "popupContent": "Какое-то описание",
  "icon": "green"
  },
"geometry":{
  "type": "Point",
  "coordinates": [37.60869026184082,48.8507382697713]
  }
}

Part of getting GeoJSON data

function onEachFeature(feature, layer) {
    if (feature.properties && feature.properties.popupContent) {
        layer.bindPopup(feature.properties.popupContent);
    }
};

function setMarkerIcon(feature, latlng) {
    var marker = new L.Marker(latlng, {icon: set_icon(feature.properties.icon)});
    return marker
}


function getMarkers(json_url) {
    var sLayer = new L.GeoJSON.AJAX(json_url, {
        onEachFeature: onEachFeature,
        pointToLayer: setMarkerIcon,
    });
    return sLayer
}

Add a search control to the map

markersLayer = getMarkers('ololo.olol/data.geojson');
map.addControl( new L.Control.Search({
        layer: markersLayer,
        propertyName: 'name',
    }) );

Searching on the 'name' field works just fine.
This is where my problems start, I don't understand how to add a second set of coordinates to the search.
For example, if you combine the sets into a group

markersLayer0 = getMarkers('ololo.olol/data0.geojson');
markersLayer1 = getMarkers('ololo.olol/data1.geojson');
groupLayer = new L.LayerGroup();

map.addControl( new L.Control.Search({
        layer: groupLayer ,
        propertyName: 'name',
    }) );

map.addLayer(groupLayer );
groupLayer .addLayer(markersLayer0);
groupLayer .addLayer(markersLayer1);

Here the search stops working on any of the layers and I don’t understand how to solve this problem.
Although, judging by the examples and the sources of LeaFlet.search, it accepts " L.LayerGroup() " as input to 'layers:' and theoretically should process the group without any problems. Don't drink too hard :)

The problem was solved, the author took the pull request.
Who cares, look into the turnip and library examples.
