Please give an example of customQuery in MatchmakingRequest for Unity and json

https://docs.gamesparks.com/api-documentation/request-api/multiplayer/matchmakingrequest.html

very good answer but here i have another issue

the best way to make a custom match between 2 players is to make a custom query like this with id like this :

//player one sends a MatchMakingRequest with the participantData set to {"country":"ireland"}
{
 "@class": ".MatchmakingRequest",
 "Id": {"_Id":"...."},
 "matchShortCode": "testMatch",
 "skill": 2
} 

//player two then sends a MatchMakingRequest with the custom query set up to look for a match with the country set to Ireland.

{
 "@class": ".MatchmakingRequest",
 "customQuery": {"players.Id._Id":"...."},
 "matchData": {},
 "matchShortCode": "testMatch",
 "skill": 2
}

or the another way is on cloud code by adding the 2 players id like this :

var matchId = Spark.getMultiplayer().createMatchById(playerId1, playerId2);

Can you give an example of a MatchmakingRequest().SetCustomQuery(customQuery) in unity? Or should we use cloud code exclusively?

Example of Matchmaking request custom query in unity:

MatchmakingRequest request = new MatchmakingRequest();
request.SetMatchShortCode("CustomMatch");
request.SetSkill(0);
string jsonString = "{\"$in\":[\"5a58dd107eebc044b8ea0f57\"]}";
GSRequestData customQuery = new GSRequestData().AddJSONStringAsObject("players.playerId", jsonString);
request.SetCustomQuery(customQuery);
request.Send(OnMatchmakingSuccess, OnMatchmakingError);

 

The above custom query would be the equivalent of this in the test harness:

"customQuery":{"players.playerId":{"$in":["5a58dd107eebc044b8ea0f57"]}}

There are also more types you can add to the query. eg:

customQuery.AddInt("Key","asdf")
