Filter Transaction with value

[massimilianochiodi]

I try to filter a private ethereum transaction by content value :

Content:
Web3swift.EventParserResult(eventName: "voted", transactionReceipt: nil, contractAddress: Web3swift.EthereumAddress(_address: "0x984c457078445a7e5c95014f35c2ed57455394e8", type: Web3swift.EthereumAddress.AddressType.normal), decodedResult: ["survey_id": 164, "name": "voted", "2": 2, "_address": Web3swift.EthereumAddress(_address: "0x49d5d3a96b34ac1053bfe0073338a93fa7982305", type: Web3swift.EthereumAddress.AddressType.normal), "0": 164, "1": Web3swift.EthereumAddress(_address: "0x49d5d3a96b34ac1053bfe0073338a93fa7982305", type: Web3swift.EthereumAddress.AddressType.normal), "3": <be7c7388 1bb54029 8cf6d0d2 0b440267 1cf4f288 d670496e 07fa8993 e45526d9>, "hash": <be7c7388 1bb54029 8cf6d0d2 0b440267 1cf4f288 d670496e 07fa8993 e45526d9>, "answer": 2], eventLog: Optional(Web3swift.EventLog(address: Web3swift.EthereumAddress(_address: "0x984c457078445a7e5c95014f35c2ed57455394e8", type: Web3swift.EthereumAddress.AddressType.normal), blockHash: 32 bytes, blockNumber: 1338585, data: 32 bytes, logIndex: 0, removed: false, topics: [32 bytes, 32 bytes, 32 bytes, 32 bytes], transactionHash: 32 bytes, transactionIndex: 0)))]

Filter : "survey_id": 164 in decodedResult array bloc.
I try :

Globale.shared.keystore = try! BIP32Keystore(
            mnemonics: Globale.shared.w!.mnemonics,
            password: Globale.shared.codicefiscale,
            mnemonicsPassword: "",
            language: .italian)!
        
        var filter = EventFilter()
        
        filter.fromBlock = .blockNumber(0)
        filter.toBlock = .latest
        let id = UInt256(164)
        let parametro = "0x" + id.description
        filter.parameterFilters = [[("\"survey_id\": " + parametro + ")")]]
        
        let contratto = Globale.shared.web3!.contract(costanti.abi, at: costanti.contratto )
        do {
            let eventParser = try contratto?.getIndexedEvents(eventName: "voted", filter: filter)
            print(eventParser.debugDescription)
        } catch {
            print("Errore : " + error.localizedDescription)
        }

But obtains all transaction of event type "voted"
