"cce001" } ] },
 {"TargetUserId" : "bce002","MultipulUsers" : [ { "MultipulUserId" :
"cce002" } ] },
 {"TargetUserId" : "bce003","MultipulUsers" : [ { "MultipulUserId" :
"cce003" } ] }
]

}

{
"UserId" : "ace002",
"TargetUsers" : [
 {"TargetUserId" : "bce004","MultipulUsers" : [ { "MultipulUserId" :
"cce004" } ] },
 {"TargetUserId" : "bce005","MultipulUsers" : [ { "MultipulUserId" :
"cce005" } ] },
 {"TargetUserId" : "bce006","MultipulUsers" : [ { "MultipulUserId" :
"cce006" } ] }
]

}

//I tried
db.collections.find({
 "UserId":"ace002",
 "TargetUsers":{ "$elemMatch" : { "TargetId" : "bce005" } }

})

// result
{
"UserId" : "ace002",
"TargetUsers" : [
 {"TargetUserId" : "bce004","MultipulUsers" : [ { "MultipulUserId" :
"cce004" } ] },
 {"TargetUserId" : "bce005","MultipulUsers" : [ { "MultipulUserId" :
"cce005" } ] },
