我有一個(gè)包含日期對(duì)象的文檔。初始化 Firestore 的代碼： FirebaseFirestore fireStore = FirebaseFirestore.getInstance();        FirebaseFirestoreSettings settings = new FirebaseFirestoreSettings.Builder()                .setTimestampsInSnapshotsEnabled(true)                .build();        fireStore.setFirestoreSettings(settings);        firestore = fireStore;查詢代碼：FirebaseFirestore db = FireStoreUtils.getInstance();Query query= db.collection(viewType.collectionName());        query.whereLessThan("endDate", new Date());         return query.orderBy(viewType.sortProperty()).limit(PAGE_SIZE);我總是得到所有的記錄，看起來(lái) where 子句沒(méi)有得到應(yīng)用。在 Firebase 控制臺(tái)上，我看到endDate存儲(chǔ)為時(shí)間戳。來(lái)自 Firebase 控制臺(tái)的文檔：createdDate: null (null)description: "desc" (string)endDate: February 3, 2019 at 11:18:58 PM UTC-8 (timestamp)id: "-7475596197450085332" (string)title: "title"
