Given documents

"_id" : ObjectId("5d0ca1443c26b8790baa8230"), "title" : { "EN" : "Toaster", "FR" : "Toasteur" } }

{ "_id" : ObjectId("5d0ca19ce04a4c790b98dd6b"), "title" : { "EN" : "Electric car", "FR" : "Voiture électrique" } }

{ "_id" : ObjectId("5d0ca1bae04a4c790b98dd6c"), "title" : { "EN" : "Window", "FR" : "Fenêtre" } }

And a index definition

var idx = {

"analyzer": "lucene.standard",

"searchAnalyzer": "lucene.standard",

"mappings": {

"dynamic": false,

"fields": {

"title": {

"type": "document",

"fields": {

"EN": {

"type": "string",

"analyzer": "lucene.simple"

},

"FR": {

"type": "string",

"analyzer": "lucene.simple",

"multi": {

"mySecondaryAnalyzer": {

"type": "string",

"analyzer": "lucene.french"

}

}

}

}

}

}

}

};

How would a $searchBeta path construction look like to search across all indexed fields (EN and FR)?
